The nurse is caring for a client diagnosed with pneumonia. The client's arterial blood gas results identify decreased level oxygen and other laboratory work reveals an increase in lactic levels. How will the nurse interpret these findings?
Hypoxemia (hypoxemia refers to a reduction in PO2 of the arterial blood & if the PO2 of the tissues falls below a critical level, aerobic metabolism ceases and anaerobic metabolism takes over, with formation and release of lactic acid)
An older adult man has moved to a long-term care facility, and the nurse is performing a medication reconciliation. The resident's current medication regimen includes alfuzosin. After considering the most likely indication for this drug, the nurse should include what potential problem in the resident's interdisciplinary plan of care?
Impaired urinary elimination (alfuzosin is classed as a nonreceptor subtype selective alpha-1 adrenergic blocker also used to treat BPH & impaired urinary elimination is the hallmark of BPH)
A client is brought to the emergency department and immediately diagnosed with a tension pneumothorax. The priority intervention would be:
Insertion of a large-bore needle or chest tube
Which statement accurately describes as aspect of serum sickness?
Is a delayed hypersensitivity reaction (serum sickness reactions are also often caused by drugs, symptoms usually develop within 7-10 days and include urticaria, lymphadenopathy, myalgia, arthralgia, and fever, & the reaction is usually resolved within a few days but may be severe or even fatal)
What is the most effective method used to monitor clients with asthma that they can use at home?
Peak-flow monitor
A client has been prescribed a medication to decrease the nighttime episodes of bronchoconstriction and prevent asthma attacks. What type of medication does the nurse suspect has been prescribed?
Leukotriene modifiers (they improve symptoms & pulmonary function tests, decrease nighttime symptoms, & decrease the use of beta-2 adrenergic drugs)
Which would bee most important to assess in a client receiving testosterone for a prolonged period of time?
Liver function studies (clients on long-term therapy with androgens should have hepatic function tests monitored regularly due to the increased risk of hepatocellular cancer)
The nurse is reviewing laboratory values of a 70-year-old female client and observes the client's low-density lipoprotein (LDL) level is elevated. The nurse understands a possible reason for this is:
Long-term estrogen deprivation (estrogens affect the composition of the plasma lipoproteins & they produce an increase in HDL, a slight reduction in LDL, and a reduction in cholesterol levels)
A group of students are reviewing information about antihistamines. The students demonstrate understanding of the information when they identify which agent as a second generation antihistamine?
Loratadine
Older adults are very susceptible to pneumonia in all its varieties. The symptoms that older adults exhibit can be very different than those of other age groups who have pneumonia. What signs and symptoms are older adults with pneumonia less likely to experience than people with pneumonia in other age groups?
Marked elevation in temperature
Rhinosinusitis-medications
Nasal decongestants
Pseudoephedrine (Sudafed) is prescribed for a client suffering from nasal and sinus congestion. What is the most important assessment the nurse should complete before the client leaves the clinic to purchase the medication?
Obtain the client's blood pressure (Decongestants are used cautiously in clients with a history of hypertension because of the vasoconstrictive effects of the drug)
A postmenopausal women is administered estradiol for the purpose of preventing which condition?
Osteoporosis
Kalie, age 18, is prescribed progesterone for the treatment of primary amenorrhea. Which adverse effect would need to be reported immediately to the health care provider?
Pain in one leg (this could indicate thrombus formation)
After teaching a group of students about bisphosphonates, the students demonstrate understanding of the information when they identify which drug as an example?
Pamidronate
Expectorants (Guifensen)-expected pharmacological action
Promotes increased cough production by increasing & thinning mucous secretions = allows client to decrease chest congestion by coughing out secretions
The nurse is educating a client suffering from advanced emphysema on how to improve expiratory flow rates. Which breathing technique would the nurse describe as most effective?
Pursed-lip breathing (this breathing technique increases expiratory airway pressure and therefore enables an increased exhalation volume by keeping the alveoli open)
The nurse is teaching a group of clients with allergic rhinitis (hay fever) about medication use. What would be the most essential information to give these clients about preventing possible drug interactions?
Read drug label before taking OTC medications (in order to avoid inadvertent overdose)
A client, experiencing respiratory distress related to bronchi constriction, will benefit from what therapeutic action provided by anticholinergic medication therapy?
Relaxation of smooth muscle (anticholinergics are used as bronchodilators because of their effect on the vagus nerve, resulting in relaxation of smooth muscle in bronchi, which leads to bronchodilation)
A client is being evaluated for a possible diagnosis of emphysema. What client characteristic should the nurse monitor to provide evidence of the disorder?
Respiratory expiration (COPD is caused by emphysema & chronic bronchitis-both of which result in airflow obstruction on expiration as well as over inflation of the lungs and poor gas exchange)
When describing the effects of second-generation antihistamines, which would the nurse address as being decreased?
Sedation
A client diagnosed with COPD has been prescribed bronchodilators by nebulizer for home use. What should the nurse teach the client to do to best assure effective use of the nebulizer?
Sit in a fully upright position when administering the medication
The nurse has completed teaching a client about the prescribed upper respiratory drug. The nurse determines additional teaching is warranted when the client chooses which finding as requiring further assessment?
Sputum appears clear (clear sputum is normal-the health care provider should be notified if the type of cough changes, sputum changes, color or increases, and shortness of breath occurs)
Antitussives (Dextromethorpan)-expected pharmacological action
Suppresses cough by depressing the cough center in the medulla oblongata or the cough receptors in the throat, trachea, or lungs
The nurse is caring for a client who has been taking prednisone for the treatment of asthma. The nurse is monitoring the client for increased levels of stress. When glucocorticoid levels are increased, what symptoms should the nurse monitor for?
Tachycardia
A client diagnosed with benign prostatic hypertrophy (BPH) is prescribe tamsulosin. The client communicates with the nurse about a friend that was prescribed sildenafil for his BPH. Which is the nurse's best response regarding the difference in the use of the two drugs for BPH?
Tamsulosin relaxes muscles in the prostate and bladder & increases ability to urinate
A client reports impotence and a lack of sexual desire. What medication does the nurse anticipate educating the client about?
Testosterone (used to treat androgen deficient states and in adult and post pubertal males, it is used to reestablish and maintain masculine characteristics and functions)
A 56-year-old client is prescribed fexofenadine for relief of symptoms associated with allergic rhinitis. Which finding in the client's medical record would be of concern?
The client has increased BUN and creatinine levels (this would indicate renal impairment and place the client at risk for toxicity of this medication & fexofenadine should be used with caution in clients with renal impairment because the drug's half-life is prolonged in these clients)
A client has experienced an atelectasis in the left lung. What explanation should the nurse provide the family regarding the cause of this condition?
The collapse of some of the alveoli in the left lung occurred as a result of outside pressure pushing against them (atelectasis is the collapse of once-expanded alveoli can occur as a result of outside pressure against the alveoli)
A 37-year-old woman has just experienced the end of a long-term relationship and has expressed a desire to begin using oral contraceptives. What aspect of this woman's current health status would contraindicate this treatment?
The woman takes an antiplatelet medication for coronary artery disease
Why are inhaled steroids used to treat asthma and COPD?
They act locally to decrease release of inflammatory mediators (when administered by inhalation, steroids decrease the effectiveness of inflammatory cells which causes decreased swelling associated with inflammation & promotion of beta-adrenergic receptor activity that can promote smooth muscle relaxation & inhibit bronchoconstriction)
Expectorants elicit their effect by which mechanism?
Thinning respiratory secretions
The nurse is educating the client about the use of pseudoephedrine. Which medication should the client be cautioned about taking concurrently with pseudoephedrine?
Thyroid preparations (thyroid preparations have the tendency to increase the risk of arrhythmias)
The nurse administers a glucocorticoid medication to a client with pneumonia. Which of these does the nurse teach the client is the purpose of the medication?
To decrease airway inflammation
A client is having an anaphylactic reaction to an insect sting. What type of hypersensitivity reaction is the client experiencing?
Type I
A 36-year-old woman is attending a lecture on women's health issues. The woman asks the nurse giving the lecture to identify steps that she can take to prevent osteoporosis. What might the nurse recommend?
Walk 30 minutes every day (regular weight-bearing exercise helps to strengthen bones, reducing the risk of osteoporosis)
The nurse is providing education to a client who has been newly diagnosed with osteoporosis. How should the nurse describe the role of the parathyroid on the development of the disorder?
When there is too much parathyroid hormone, the bones release their calcium into the blood at a rate that is too high, resulting in bones which have too little calcium (osteoporosis is associated with hyperparathyroidism is caused by the high parathyroid hormone that is secreted by the overactive parathyroid gland(s) & this excess hormone acts directly on the bones to remove calcium from the bones)
Pneumothorax-treatment
breathing tube
A nurse is providing education to a 56-year-old man who is admitted to the emergency department with an acute asthma attack. The nurse's initial assessment reveals that the patient has a history of pneumonia, drinks large quantities of coffee, and eats a high-calorie diet. Albuterol is prescribed for him. The important consideration when the nurse is preparing a teaching plan will be that the patient
has a high coffee intake (caffeine has sympathomimetic effects that may increase the risk for adverse effects with albuterol & the nurse should assess the patient's intake of caffeine through coffee, tea, soda, cocoa, candy, and chocolate)
An individual has sensitivity to perfumes and experiences shortness of breath when exposed to them. This occurs because:
stimulation of irritant receptors causes bronchoconstriction
