ACE-Inhibitor mechanism of action
ACE-Inhibitors inhibit the conversion of angiotensin-1 to its more active form, angiotensin-2. ACE-Inhibitors counteract or inhibit all of the pharmacological effects of angiotensin-2. Thus ACEinhibitors cause vasodilation, decrease aldosterone levels, Na+ & fluid wasting & K+ retention
A woman is receiving physical therapy after surgery to repair a hip fracture. She tells the therapist before therapy begins that she expects therapy to be very painful. She rates her pain as 1 on a scale of 1 to 10 before therapy. Three minutes into the treatment session, the patient complains of excruciating pain rated as 10 and says she cannot tolerate exercise any longer. The therapist is concerned with the amount of pain, because severe pain is not expected during that form of exercise. The therapist considers the patient could be experiencing: 1) Phantom limb pain. 2) Ineffective pain medication. 3) A nocebo effect. 4) A complication from the surgery.
ANS: 3 The nocebo effect is a demonstration of the power of the mind to create bodily distress. The patient was expecting the treatment to be very painful, and this tends to increase the treatment discomfort. Phantom limb pain is sometimes experienced after an amputation but has nothing to do with surgery to repair a hip fracture. There is no evidence that the patient's pain medication is ineffective or that she is experiencing a complication from surgery.

An elderly client with a history of COPD is having difficulty sleeping and does not wish to see a medical practitioner. Which of the following strategies should the nurse discourage the client from using, or urge him to see a physician before beginning the therapy? The client has not used any of these therapies in the past. Choose all that apply. 1) Aromatherapy 2) Tai chi 3) Yoga 4) Melatonin
ANS: 3, 4 Aromatherapy is known to be safe, and may be effective. Tai chi is safe for older adults and may be effective for sleep. Yoga is possibly effective for sleep, but it is physically rigorous, so it has the potential to be harmful for older adults, who may have a variety of chronic conditions. The client should see a physician before beginning yoga. Melatonin is effective for certain sleep disorders, but it does interact with several prescription drugs. Therefore, the client should not take melatonin without consulting a physician. PTS:1DIFgrinifficult REF: pp. 9, 11, 14, 15; not stated directly in text: critical thinking required
A client wishes to avoid taking blood pressure medications. He is watching his diet and exercising. In addition, a CAM therapist has recommended an alternative therapy that will allow him to learn voluntary control over his blood pressure. What type of therapy is the therapist probably recommending? a) Homeopathy b) Naturopathy c) Biofeedback d) Hypnosis
ANS: C Biofeedback is a technique by which people learn voluntary control over typically involuntary activities. Homeopathy is based on an understanding of how the body heals itself and an acceptance that all symptoms represent the body's attempt to restore itself to health. Naturopathy is the belief that nature and each living being have the innate ability to establish, maintain, and restore health. Hypnosis is a trancelike state characterized by relaxed brain waves, hypersuggestibility, and heightened imagination. Hypnosis has been used to promote relaxation, weight loss, and smoking cessation and to suppress various symptoms.

Hyperkalemia. Can be life-threatening. Monitor K+ closely if using with ACE-I or ARB. Use extreme caution if giving K+ supplements to patients receiving potassium-sparing diuretics! Spironolactone, since it chemically resembles some sex steroids, may cause gynecomastia in men and menstrual irregularities & deepening of voice in females.
Prolonged use of any diuretic can cause? Why does this matter?
Hypokalemia, potassium is needed for normal heart function
ACE-Inhibitors Adverse effects
Hypotension (especially with the first dose - give a test dose of captopril to be safe) Hyperkalemia (elevated serum K+) - due to aldosterone effects Bradykinin related side effects Dry hacky cough (can reduce dose & retry) [5%] Non-allergic rash Rarely angioedema (swelling of lips & face) - immediately discontinue! Contraindicated in pregnancy
Non-selective beta-blockers
Hypotension, sexual impairment, nightmares, some HDL & Tg (minor with chronic use). Heart failure, reduced cardiac output (fatigue) arrhythmias, & bradycardia (b1 mediated). Peripheral vasoconstriction (b2 mediated): Not a problem for most people unless there is a history of peripheral vascular disease (PVD), Reynaud's, or non-healing ulcers where there is already some decreased peripheral blood flow. Bronchoconstriction (b2 mediated): This bronchoconstriction is not a problem for most patients. However, patients with COPD or asthma may be adversely affected. May mask signs & symptoms of hypoglycemia in diabetics. Metabolism disturbances (b2 mediated): Lead to decreased release of glucagon & decreased liver glycogenolysis (decreased conversion of glycogen to glucose). This can decrease a diabetic's ability to correct hypoglycemia. Again, this is normally not a problem for most people, but can cause prolonged hypoglycemia in diabetics. Do Not Stop Abruptly!! May cause rebound angina, arrhythmias, heart attack, & DEATH

A client wishes to avoid taking blood pressure medications. He is eating a healthy diet and exercising regularly. In addition, a CAM therapist has recommended an alternative therapy that will allow him to learn voluntary control over his blood pressure. What type of therapy is the therapist probably recommending? 1) Homeopathy 2) Naturopathy 3) Biofeedback 4) Hypnosis
ANS: 3 Biofeedback is a technique by which people learn voluntary control over typically involuntary activities. Homeopathy is based on an understanding of how the body heals itself and an acceptance that all symptoms represent the body's attempt to restore itself to health. Naturopathy is the belief that nature and each living being have the innate ability to establish, maintain, and restore health. Hypnosis is a trancelike state characterized by relaxed brain waves, hypersuggestibility, and heightened imagination.

ANS: 4 Many herbs are known to interact with medications and to affect some disease processes adversely. Nurse practice acts do require RNs to assess patients but do not specifically require monitoring of drug dosages. Herbal products do need to be evaluated in research, and medication records must be accurate, but they do not provide the rationale for patient data collection.

The health and well-being of a holistic nurse in relation to helping patients constitute an important part of the healing process. A method that would be helpful to nurses in fostering their own health and the health of their patients is: a) Role modeling healthy behaviors b) Avoiding discussions on personal behaviors c) Working and acting in isolation d) Setting goals for the patient
ANS: A A holistic nurse role models healthy behaviors for her patients. Practically speaking, a holistic nurse understands that unless her own health is balanced, it is difficult to sustain the energy necessary to be a constructive presence and an effective practitioner. Stress evokes negative physiological responses in the body, which could lead to illness. Working in isolation does not allow one to gain the perspectives and insights of others in a commonly shared experience.
The nurse in a women's health clinic, educates patients about the benefits of probiotic therapy. Today, the nurse is working with a patient complaining of recurrent vaginal yeast infections. The patient's laboratory tests confirm Candida albicans. Which statement helps the nurse to determine that the patient needs more teaching regarding probiotic therapy? a) "If I eat yogurt, I will not get any more yeast infections." b) "I can eat yogurt and it will reduce my yeast infections." c) "Eating yogurt once a day will help to balance my natural body flora." d) "I can take probiotics once I read their labels to ensure the bacteria are live."
ANS: A Eating yogurt does not eliminate yeast infections permanently or completely take away the potential for them to occur. Eating a probiotic, such as yogurt, can reduce vaginal yeast infections if eaten on a regular basis by establishing and supporting healthy body flora. Probiotics are most helpful when the bacteria are live and of a sufficient number to reestablish healthy amounts of flora. The statement that probiotics will prevent future infections is false, so the patient requires teaching on this point.
The health clinic nurse is interviewing a new patient. The nurse asks questions about the patient's self-care and about his healthcare providers. Which statement is likely to yield the most information from the patient regarding the use of CAM? a) "Many people go to a medical provider and other healers, as well. Please tell me about the practitioners and healers you use." b) "Some people go to both medical and nonmedical providers for healthcare. Do you use both?" c) "Many people only go to a medical physician. Tell me about the practitioners you see for healthcare." d) "Some people go to different types of CAM healers. You don't use CAM, do you?"
ANS: A For therapeutic questioning, the nurse should use open-ended questions to yield the most information. The question ending in "Do you use both?" is a yes/no question that will likely elicit very little information. Although the option ending in "Tell me about the practitioners you see for healthcare," seems open ended, the negative use of "only" ("only go to a medical physician") implies that there is not another acceptable answer, thus decreasing the information the patient may share. "You don't use CAM, do you?" is a negative, closed question. It suggests that the patient should answer "No," and almost certainly will elicit a one-word answer.
A client has a diagnosis of chronic pain. The physician has prescribed tramadol hydrochloride (Ultram) for the pain. The patient also receives therapeutic touch (TT) from a practitioner three times a week. In this situation, TT is considered to be which of the following? a) A complementary modality b) An alternative modality c) A placebo response d) Holistic healthcare
ANS: A A complementary modality is one that is used alongside traditional medical care. The patient receives prescription medication from a physician and also receives TT. An alternative modality is one that is used instead of traditional medical care. A placebo response is the client's expectation that a treatment will be effective. Holistic healthcare uses the concept of holism to focus on the relationships among all living things.

Select all that apply. a) They are almost all readily available to consumers. b) They can be practiced as self-care measures. c) It is easy to know what dosage is being obtained from a product. d) Products on the market have been proved to be safe to use.
ANS: A, B Biologically based therapies use substances found in nature, such as food, herbs, vitamins, and scents used in aromatherapy. These therapies are readily available and are often practiced as self-care measures, so people who do not wish to see a practitioner may not need to do so. The U.S. Food and Drug Administration (FDA) regulates biologically based therapies and is developing guidelines for good manufacturing practices (GMPs).

Select all that apply. a) Interaction with other medications b) Standardization of herbal preparations c) Lack of standardization of herbal preparations d) Lack of a formulary e) Reduced chance of toxicity
ANS: A, C, D Herbal therapies are not as regulated or standardized as Western medications. The major risks of herbal therapies are the lack of a formulary, the lack of standardization, the potential for interactions that are not identified, and the potential for toxicity as a result of dosages and interactions.
Through the use of the nursing process, holistic healthcare implemented by nurses includes which of the stated activities? Select all that apply. a) Health promotion b) Illness accentuation c) Health maintenance d) Education
ANS: A, C, D Holistic healthcare includes illness prevention, not accentuation, along with health education, health promotion, health maintenance, and restorative rehabilitative care.
The nurse is caring for a patient with severe, chronic headaches. According to a recent medical work-up, there "is no definitive physiological reason for these headaches." The nurse counsels the patient about alternative therapies for headaches, knowing that: a) Homeopathic medications eliminate migraine and other chronic headaches b) Acupuncture is more effective than medication in relieving chronic headaches c) Western medicine has no alternative treatment for severe, chronic headaches d) There is no palliative care for chronic headaches without physiological basis
ANS: B Acupuncture has been shown to more effectively relieve chronic headaches than medications. Homeopathic medicine is person specific and not disease/symptom specific—that is, it cannot be said that it affects headaches in a specific way. Western medicine does have other alternative treatments for severe and chronic headache management (e.g., biofeedback, botulinum toxin). There is palliative care for chronic headaches to manage the process rather than effecting a "cure."
The nurse is caring for a patient who after removal of a tumor had radiation therapy. The patient, without consulting his primary provider, added nutritional therapy and the use of acupuncture. The treatments chosen by the patient are examples of what type of treatments? a) Alternative modalities b) Complementary modalities c) Integrative healthcare d) Conventional biomedical therapies
ANS: B Complementary modalities (i.e., nutritional therapy and acupuncture) are used in conjunction with traditional medical care (the radiation treatments). Alternative modalities are used instead of conventional medical therapies. Integrative modalities are therapies that are proved to be effective and safe when combined with or integrated into conventional therapies. Conventional biomedical therapies include radiation therapy.
The nurse understands that CAM therapies are popular with many patients. What is the most important thing for the nurse to know regarding safe use of CAM therapies? CAM therapies a) Must be sensitive to the patient's culture b) Need to be tested to establish their effectiveness c) Should be determined by the patient d) Chosen by the patient can bypass testing
ANS: B Patients may use CAM therapies even if there is no accurate evidence on which to base their effectiveness or safety. Therefore, the nurse needs to look at empirical research to guide the nurse, patient, and healthcare provider in using these therapies. The other responses negate the importance of research data in the use of CAM, although they do suggest issues that can improve the effectiveness of any therapy (i.e., cultural sensitivity, the patient wants to use them).
Which groups of people choose CAM more often than do others? Select all that apply. a) Men b) Women c) People younger than 18 years of age and older than 70 years of age d) People older than 18 years of age and younger than 70 years of age e) Caucasians
ANS: B, D, E Caucasian women over 18 years of age and younger than 70 years of age are the main group that uses CAM. Although the other groups do use CAM, they do not use it as much as those groups.
The nurse is caring for a patient, who recently emigrated from India. The patient states the reason for the visit is for a well-patient visit. While taking the patient's history, the nurse ascertains that the patient is using ayurvedic herbal remedies. Which statement below assists the nurse to determine whether the patient understands the pros and cons of these herbal remedies? a) "I can continue to order these herbal remedies from the shop in India where I have always purchased them." b) "I can order these herbal remedies from any Internet source selling them." c) "I should order these herbal remedies over the Internet from an FDA-approved site." d) "I have had no problems from taking these herbal remedies, so I can continue their use."
ANS: C Ayuvedic herbal remedies are frequently combined with metals that can be harmful to the patient. Purchasing them from an unregulated shop or Web site increases the chances of there being higher levels of toxic metals in the herbal mixtures. Therefore, the patient should purchase these herbal remedies only from an FDA-approved Web site source. Also, because the patient believes there is no problem with taking these unregulated remedies, the nurse must educate him about the potential issues with this.
Herbal products are very popular worldwide for prevention and treatment of illness. As a nurse you should: a) Advise patients to purchase herbal products from the least expensive source b) Inform patients that research conclusively states that herbs are safe c) Learn about herbal therapies and include them in questions when taking a patient's history d) Disregard patients' use of herbal products, as their use will not impact traditional medicine
ANS: C Because herbal products are readily available and widely used, you should learn about herbal products and include them in questions when taking a patient's history. The National Center for Complementary and Alternative Medicine (NCCAM) offers extensive material on herbal products for professionals and consumers. Advise patients to purchase herbs from a reliable source and seek advice from credentialed practitioners when incorporating herbs into their care.
The concept of holism focuses on which of the following? a) Relationship between nurse and patient b) Practice of spiritualism c) Relationships among all living things d) Totality of the body
ANS: C The concept of holism focuses on the relationships among all living things.
A woman is receiving physical therapy after surgery to repair a hip fracture. She tells the therapist before therapy begins that she expects therapy to be very painful. She rates her pain as 1 on a scale of 1 to 10 before therapy. Three minutes into the treatment session, the patient complains of excruciating pain rated as 10 and says she cannot tolerate exercise any longer. The therapist is concerned with the amount of pain, because severe pain is not expected during that form of exercise. The therapist considers the patient could be experiencing: a) Phantom limb pain b) Ineffective pain medication c) A nocebo effect d) A complication from the surgery
ANS: C The nocebo effect is a demonstration of the power of the mind to create bodily distress. The patient was expecting the treatment to be very painful, and this tends to increase the treatment discomfort. Phantom limb pain is sometimes experienced after an amputation but has nothing to do with surgery to repair a hip fracture. There is no evidence that the patient's pain medication is ineffective or that she is experiencing a complication from surgery.
An elderly client with a history of COPD is having difficulty sleeping and does not wish to see a medical practitioner. Which of the following strategies should the nurse discourage the client from using, or urge him to see a physician before beginning the therapy? The client has not used any of these therapies in the past. Select all that apply. a) Aromatherapy b) T'ai chi c) Yoga d) Melatonin
ANS: C, D Aromatherapy is known to be safe, and may be effective. Tai chi is safe for older adults, and may be effective for sleep. Yoga is possibly effective for sleep, but it is physically rigorous, so it has the potential to be harmful for older adults, who may have a variety of chronic conditions. The client should see a physician before beginning yoga. Melatonin is effective for certain sleep disorders, but it does interact with several prescription drugs. Therefore, the client should not take melatonin without consulting a physician.
A client tells the nurse that he is having difficulty sleeping. He says, "I don't want to use sleeping pills, but I'm thinking about getting some melatonin." Which of the following is most important for the nurse to include in a response to the client? a) "Melatonin is an effective treatment for certain sleep disorders." b) "Melatonin appears to be a relatively safe sleep aid for most people." c) "You may experience some side effects, such as elevated blood pressure." d) "Before taking melatonin, you should consult your primary care provider."
ANS: D All of the statements are true about melatonin; however, side effects are rare. It is most important to consult the primary care provider because melatonin is known to interact with other medications, including prescription medications. Therefore, the client should talk with the provider about this possibility.
A patient is receiving healthcare focused on his illness and counteracting his symptoms. What type of healthcare is he receiving? a) Holistic b) Integrative c) Complementary d) Allopathic
ANS: D Allopathic care is conventional medical care focused on counteracting symptoms. Holistic healthcare uses the concept of holism to focus on the relationships among all living things. Integrative healthcare encompasses all traditional and alternative health practices used by a patient. Complementary healthcare is alternative care used in conjunction with traditional medical care.
A patient has been taking herbal remedies to decrease blood pressure. The patient is convinced that this has reduced his blood pressure and he refuses to take a prescribed antihypertensive medication. The nurse checks his blood pressure reading during an office visit, with the following results: Left arm: 130/94, 140/86, and 160/90 mm Hg. With this information, what is the nurse's best response to the patient's refusal to take antihypertensive medications? a) "I see that you are correct; your blood pressure readings do not indicate hypertension." b) "Your blood pressure is elevated, so you will need to take a prescribed antihypertensive." c) "Your blood pressure is within normal limits and does not need anything for it." d) "Your blood pressure is elevated. It is important to discuss this with your doctor."
ANS: D The nurse identifies that these blood pressure readings are elevated and correctly suggests the discussion with the physician. The nurse is not the person to determine potential therapies for the patient. The nurse cannot tell the patient he is correct and does not have hypertension because his vital signs do not support that. The patient's blood pressure is not within normal limits.
The nurse is reviewing the protocol for administration of IV adenosine (Adenocard). What is the MOST important nursing intervention to remember when giving this medication?

A nurse has just completed inventory on the controlled substances on the unit, has completed necessary documentation, and locked the cabinet. He or she walks away, leaving the locked cabinet on the counter in an open workstation. What step has the nurse not completed? 1. Double-locking the controlled substances 2. Putting them inside a cabinet 3. Having a second witness sign the documentation 4. Passing keys to the locked cabinet to the next charge nurse
Answer 1 Option 1: All controlled substances must be double-locked (stored in locked drawers, in a second locked area) Option 2: Controlled substances can be put inside a cabinet, but they should be secured appropriately. Option 3: A second signature is not needed unless the facility requires it. Option 4: Inventory typically is conducted at the beginning of the shift, so passing keys off to another nurse is not needed.
Which are examples of parenteral administration of medication? Select all that apply. 1. Intramuscular 2. Intravascular 3. Inhaled 4. Oral suspension 5. Topical application
Answer 1, 2 Option 1: Intramuscular medications are injected into a muscle, which is parenteral administration. Option 2: Intravascular medications are injected into a vein, which is parenteral administration. Option 3: Inhaled medication is not injected and is not parenteral administration. Option 4: Oral suspension is not injected and is not parenteral medication. Option 5: Topical application of medication is not parenteral, as it is not injected.
The pediatrician has ordered erythromycin 20 mg/kg of body weight for a 55-pound client. The medication on hand is 250 mg tablets. How many tablets will be administered to this client?
Answer is 2 (DO NOT SAY TABLETS ON QUIZ AS IT WILL MARK IT WRONG... DUMB...) Convert weight to kg: 55 lb/2.2 kg = 25 kg Determine amount needed: 20 mg x 25 = 500 mg Determine how many tablets needed to get 500 mg: 500/250 = 2
Once the student nurse has researched the new antibiotic prescribed to treat the client's pneumonia, he or she feels more information is needed to plan nursing interventions based on side effects of the drug. What resource would be best suited to obtain this information? 1. Nursing drug handbook 2. The National Formulary 3. Physician's Desk Reference 4. A pharmacopoeia
Answer: 1 Option 1: A nursing drug handbook provides important information regarding the drug, how it is prescribed, side effects, and nursing interventions. Option 2: The formulary identifies the therapeutic value of drugs as well as their formulas and prescriptions, but may not be the best for nursing intervention recommendations. Option 3: While an excellent resource, the PDR contains information on dosing, routes of administration, and side effects, but does not include nursing interventions. Option 4: The Unites States Pharmacopoeia (USP) is a directory of drugs approved by the Food and Drug Administration (FDA) and includes a list of the physical and chemical composition of each drug.
A client has been prescribed an antibiotic that has side effects including nausea, vomiting, abdominal pain, and diarrhea. What nursing intervention would be appropriate for this client? 1. Instruct the client on side effects, what to report, and when. 2. Instruct the client on documenting bowel movements, consistency, and frequency. 3. Document that the client reports no nausea, vomiting, abdominal pain, or diarrhea. 4. State that the client will be free from side effects including nausea, vomiting, and diarrhea
Answer: 1 Option 1: As a primary nurse, the responsibility is to educate the client on possible side effects including what to look for, what to report to nursing staff, and when. Option 2: Having clients document bowel movements is not needed; if monitoring is needed, it should include the nursing staff. Option 3: Making statements regarding what has occurred is an evaluation. Option 4: Making a statement regarding what will or should happen is an outcome, not an intervention.
The student nurse is about to administer a rectal suppository to an older adult. What advice should the preceptor offer this student in regard to older clients and rectal suppositories? 1. Due to poor sphincter control, a bed pan should be used during the procedure. 2. Suppositories are only inserted ½ in. in older adults. 3. Suppositories may have to be pushed a little harder due to a tightened rectal sphincter. 4. The buttocks may need to be held together to ensure the suppository remains in place.
Answer: 1 Option 1: As older adults lose control over sphincter muscles, it is wise to use a bed pain while inserting the suppository in the event of loss of control. Option 2: In all adults, it is suggested to insert rectal suppositories 1 to 3 in. into the rectum, past the internal sphincter. Option 3: Suppositories should never be forced, as it could mean blockage due to fecal matter that will prevent absorption of medication. Option 4: Holding the buttocks together is suggested in pediatric clients, not for older clients.
Which describes drugs with limited medical use and high potential for abuse or addiction? 1. Controlled substances 2. Prescription drugs 3. Narcotics 4. Placebo drugs
Answer: 1 Option 1: Controlled substances are available by prescription only and are used with caution. Option 2: Prescription drugs is a broad category of drugs only available with a medical order. Option 3: Narcotics are a category of potentially addictive drugs. They are, however, medically useful for pain control. Option 4: Placebo drugs have no effect and are given in some clinical trials. Their use is controversial and considered a violation of patient rights.
Why are lipid-soluble drugs used for sedation? 1. They can pass through the blood brain barrier. 2. They cannot be broken down by acids, preventing the medication from being diluted before it reaches the nervous system. 3. They release small amounts for absorption over several hours. 4. They are rapidly absorbed from the GI tract and take effect faster.
Answer: 1 Option 1: Due to the ability of fat-soluble drugs to attach to lipids, they can easily pass through the blood brain barrier and effect sedation. Option 2: Enteric-coated medication cannot be broken down by GI acids that prevent dilution before entering the intestines. Option 3: Time-released or sustained-release formulas release small amounts of the medication over a period of several hours, allowing for absorption over a longer period of time. Option 4: Water-soluble drugs are rapidly absorbed from the GI tract, which has a quicker effect.
A client presents to the emergency department with severe pain related to a kidney stone. In order to obtain adequate pain relief quickly, which is the most rapid and effective route to administer pain medications? 1. Intravenous 2. Intramuscular 3. Oral administration 4. Subcutaneous injection
Answer: 1 Option 1: Intravenous administration of medication directly injects the medication into the bloodstream, which has the fastest action. Option 2: Intramuscular injection must be absorbed into muscle tissue before being taken up by the bloodstream. This is not the fastest route. Option 3: Oral administration of medications must be processed through the stomach, and then absorbed into the bloodstream through the digestive tract. This is not the fastest route of administration. Option 4: Subcutaneous injections are absorbed into the soft tissues before being disbursed into the bloodstream.
To whom can a nurse delegate the administration of ophthalmic solutions? 1. LPN/LVN 2. NAP 3. PA 4. ANP
Answer: 1 Option 1: LPN/LVNs are authorized to administer ophthalmic solutions. Option 2: Nurses cannot delegate ophthalmic administration to NAPs, as it is not in their scope of practice. Option 3: A physician's assistant would not normally take direct orders from a charge or unit nurse. Option 4: Advanced nurse practitioners can delegate this responsibility, but they are typically not taking direct orders from a charge or unit nurse.
A client is brought into the emergency department in shock due to a trauma. What method would be the most effective route for administering emergency medications? 1. Intravenously 2. Intramuscularly 3. Sublingually 4. Orally
Answer: 1 Option 1: Shock reduces peripheral circulation, so administering medication directly into the bloodstream is the best method. Option 2: As peripheral circulation is reduced in shock, administering medications intramuscularly would not be effective. Option 3: Not all medications can be administered sublingually, so this would not be an effective method. Option 4: Oral medications take longer to take effect and therefore would not be the best method.
What is the benefit of using an automated dispensing system? 1. Allows for immediate availability and administration of newly prescribed and prn medications 2. Promotes independence and allows evaluation of a client's ability to manage medications safely and accurately before discharge 3. Saves nursing time and is the safest method 4. Automatic inventory of all unit medications
Answer: 1 Option 1: The computer database contains prescriptions, records, and counts of the medications for each client on the unit which allows for immediate availability of medications. Option 2: Self-administering of medications is the method that promotes independence and also gives the nurse an opportunity to evaluate for ability to self-medicate at home. Option 3: The safest method is the unit-dose method, as it involves a double-check system. Option 4: While an automated system keeps track of a client's medication and what is held within the system, this is not specifically a benefit.
Which is the usual dosing method of drugs for pediatric clients? 1. Milligrams per kilogram of body weight 2. Ounces per pound of body weight 3. Milligrams per pound of body weight 4. Ounces per kilogram of body weight
Answer: 1 Option 1: The metric system is used for calculating drug dosages for pediatric clients. Option 2: Ounces and pounds are part of the apothecary system and are not used for pediatric dosing. Option 3: Milligrams is metric and pounds is apothecary. Two different methods should not be used in drug calculation. Option 4: Ounces is apothecary and kilogram is metric; this combination should not be used to calculate dosage.

Administer laxatives or cathartics and/or enemas if ordered. 4. Report a pattern of decreasing bowel sounds. 5. Expect an absence of abdominal distention and pain.
Answer: 1, 2, 3 Option 1: By teaching the client to increase intake of fiber, he or she can deal with possible side effects of constipation easier. Option 2: Increasing fluid intake will help minimize risk for the side effect of constipation. Option 3: If needed, laxatives or enemas can be used to relieve constipation. Option 4: Intervention of bowel sounds is not indicated by the nursing diagnosis and outcome. Option 5: Making a statement of what should or will occur is an outcome, not an intervention.
A client is scheduled for an annual PPD for work. What considerations should the nurse be aware of before administering this test? Select all that apply. 1. Pregnancy 2. Previous skin reaction 3. Use of topical anesthetic 4. Fever 5. Use of an antihistamine within past 4 hours
Answer: 1, 2, 3 Option 1: If client is pregnant, PPD should be deferred and the provider alerted. Option 2: Depending on the type of reaction, further testing may be needed and the provider should be informed. Option 3: If the client has used a topical anesthetic in the location, the test should be conducted on the other arm or rescheduled. Option 4: Fever is always a consideration in any type of medication administration but typically does not affect PPD testing. Option 5: Use of an antihistamine does not have any contraindications for the testing of PPD.
Which are safety challenges related to medication self-administration in older adults? Select all that apply. 1. Opening medication containers 2. Remembering to take medications 3. Visualizing labels for correct dosing 4. Asking doctors for medications 5. Thinking medications are not needed
Answer: 1, 2, 3 Option 1: Medications for elderly adults should be provided in easy-to-open bottles. Option 2: An elderly person who has dementia may forget to take medications or forget that he or she has already taken a medication. Option 3: Elderly clients who have trouble seeing may not be able to accurately read a medication label. Option 4: Difficulty asking for medications is not associated with the elderly. Option 5: Thinking medications are not needed is not a consideration unique to the elderly.

Option 2: Rectal bleeding could indicate disease or other issues that could prevent effective medication absorption and administration. Option 3: The use of glycerin in clients with heart disease can cause irregular heart rates and other cardiovascular dysfunction. Option 4: Hemorrhoids are not considered a contraindication. Option 5: Irritation may make administration uncomfortable but is not considered a contraindication.
When preparing to administer an otic solution to a client, what should the nurse assess the client for? Select all that apply. 1. Redness 2. Cerumen 3. Drainage 4. Ear pain 5. Fever
Answer: 1, 2, 3, 4 Option 1: Erythema should be noted both inside and outside of the ear canal. Option 2: Wax buildup should be taken care of prior to administering medications. Option 3: Drainage should be noted, (color and amount) and may possibly need to be irrigated prior to administering medication in the ear. Option 4: Any ear pain the client is experiencing should be noted, and the provider will determine if the nurse is to proceed. Option 5: The client's temperature should be taken, but this is not a needed assessment directly related to administering ear medications.
How are medications detoxified from the body? Select all that apply. 1. Kidneys 2. Blood plasma 3. Intestinal mucosa 4. Lungs 5. Large intestine
Answer: 1, 2, 3, 4 Option 1: Kidneys filter and work to excrete waste, so metabolized medications from the liver can be removed here. Option 2: Blood plasma carries waste to be filtered and excreted, so metabolized medications from the liver can be removed here. Option 3: Intestinal mucosa has the ability to absorb metabolized waste from medication and transfer it to be carried for excretion. Option 4: The lungs act as a method of removing waste from the body, and metabolized medication waste can be removed this way as well. Option 5: The large intestine absorbs water but is not a viable manner for detoxifying medications from the body.
A nurse is scheduled to administer the following drugs to the client: (1) insulin subcutaneously for diabetes, and (2) morphine intravenously to relieve pain. What factors should be considered that will affect the pharmacokinetics of the drugs when administering these medications? Select all that apply. 1. Body mass 2. Gender 3. Pregnancy 4. Time of administration 5. Therapeutic effect 6. Location
Answer: 1, 2, 3, 4, Option 1: Medication dosage is based on an "average" weight for adults of 150 lbs, so anything over or under must be recalculated. Option 2: Men and women absorb medications differently due to differences in muscle mass, hormones, and fat distribution. Option 3: Pregnancy must be considered due to the teratogenic effect of some medications. Option 4: Time of administration must be considered, as some medications should be taken on an empty stomach, full stomach, and so forth. Option 5: The therapeutic effect is a factor of pharmacodynamics, not pharmacokinetics. Option 6: Route of administration is a factor; however, location is not a factor in pharmacokinetics.
Which are classification systems for drugs? Select all that apply. 1. Usage 2. How supplied 3. Body system 4. Chemical or pharmacological class 5. Manufacturer
