A Rationale: In hypokalemia, low potassium levels in the blood, can lead to muscle weakness, including respiratory muscles.

Which component of skin maintains optimal barrier function? a) Keratin b) Melanin c) Collagen d) Adipose Tissue

A Rationale: Keratin is a protein produced by keratinocytes that helps maintain optimal barrier function.

Which principle explains how loop diuretics promote diuresis? a) Osmosis b) Filtration c) Diffusion d) Active transport

A Rationale: Loop diuretics inhibit the reabsorption of sodium and water in the ascending loop of Henle. The increased sodium load in the distal tubule causes the passive transfer of water from the glomerular filtrate to urine through the process of osmosis

Which action is the nurse's priority when caring for a patient admitted for dehydration on an IV infusion of normal saline at 125 mL/hr who begins screaming, "I can't breathe!" one hour after the IV is initiated? a) Elevate the head of the bed and obtain vital signs b) Discontinue the IV and contact the primary health care provider c) Change the IV to an intermittent infusion device d) Contact the primary health care provider to obtain a prescription for a sedative

A Rationale: Normal saline will not cause an allergic reaction and a mere 125 mL in a dehydrated client will not cause pulmonary edema, so it is important to further assess the patient to determine the cause of the patient's distress. Elevating the head of the bed facilitates breathing by decreasing pressure against the diaphragm

Which action would the nurse take first for a patient with a generalized anxiety disorder? a) Remove as many stimuli from the patient's environment as possible b) Encourage the client to exercise on a daily basis c) Administer as-needed medications prescribed by the primary health care provider d) Have the patient list the behaviors used to reduce anxiety

A Rationale: Removing as many stimuli from the patient's environment helps reduce the patient's anxiety by limiting the factors that must be confronted; decreasing stimuli usually decreases anxiety

Which environment would be conducive to reducing emotional stress and providing safety for a patient diagnosed with generalized anxiety disorder? a) One in which realistic limits and controls are set b) One where all needs are met c) One where the patient's environment is kept neat and orderly One in which the patient's requests are met promptly

A Rationale: Setting realistic limits and control makes the environment as emotionally nonthreatening as is realistically possible

Which action would the nurse take first when caring for a postoperative patient who reports pain? a) Perform a focused assessment b) Provide an ice bag c) Document the patient's complaint in the chart d) Administer pain medication as prescribed

A Rationale: The first step of the nursing process is assessment; the nurse would assess the patient is make sure that the complaint of pain is not indicative of another problem that requires intervention

Which action would the nurse take after identifying that a patient's urinary output is less than 40 mL/hr over the past 3 hours? a) Assess breath sounds and obtain vital signs b) Decrease the IV flow rate and increase oral fluids c) Insert an indwelling catheter to facilitate emptying of the bladder d) Check for dependent edema by assessing the lower extremities

A Rationale: The imbalance in intake/output, with a decreasing urinary output, may indicate kidney failure. The retention of excess body fluid can precipitate the development of heart failure. Assessing breath sounds and obtaining vital signs are necessary when monitoring for these complications.

Which factor would the nurse consider in addition to physiological needs when planning care for a group of patients? a) Patient expectations b) Number of patients assigned c) Routine care time schedule d) Skill level of nursing assistive personnel

A Rationale: The nurse would consider patient expectations as well as the physiological priorities. Working closely with patients and displaying a caring attitude will increase compliance and patient satisfaction.

Which approach would the nurse use for a patient with Alzheimer disease who expresses fear and anxiety upon admission to a long-term care facility? a) Reassuring the patient with the presence of 1-2 staff members b) Exploring the reasons for the concerns c) Providing the patient with a written schedule of planned interactions Explaining to the patient why the admission to the facility is necessary

A Rationale: The patient needs reassurance, because forgetfulness blocks previous explanations; the presence of 1-2 staff members serves as a support system.

Which condition requires airborne precautions? a) Measles b) Influenza c) Clostridium difficile (C.diff) d) Bacterial meningitis

A Rationale: Varicella, measles, and tuberculosis require airborne precautions because these infections spread through small particles in the air.

1. Which action(s) would the nurse instruct an older patient to implement to ensure antibody-mediated immunity? (Select all that apply.) a) Obtain a shingles vaccination b) Receive a tetanus booster injection c) Obtain the pneumococcal vaccination d) Receive annual testing for tuberculosis e) Receive an annual influenza vaccination f) Avoid obtaining the pertussis vaccination

A, B, C, E Rationale: Because older adults are less able to make new antibodies in response to the presence of new antigens, they should receive the shingles vaccination. Older adults may not have sufficient antibodies present to provide protection when re-exposed to microorganisms, thus booster shots are encouraged. The pneumococcal and influenza vaccinations help create antibodies in response to new antigens.

Which finding in a patient seen at the outpatient clinic supports a diagnosis of an arterial ulcer? (Select all that apply.) a) Lack of hair b) Thickened toenails c) Copious ulcer drainage d) Diminished pedal pulse e) Brown skin discoloration

A, B, D Rationale: Prolonged lack of oxygen to hair follicles and toes results in hair loss and thickened toenails. Inadequate arterial perfusion results in diminished pedal pulse quality

Which assessment item(s) needs to be documented on a patient with restraints? (Select all that apply.) a) Pulse near the restrained area b) Temperature of the restrained area c) Convenience of restraining the patient d) Skin integrity surrounding the restraint e) Behavior leading to the need for restraint

A, B, D, E Rationale: Restraint use requires assessment of the body area restrained, such as pulse quality, temperature, and skin integrity. Behavior necessitating restraint should be assessed and documented.

The nurse is caring for a patient with chronic back pain. Which nursing considerations would be made when determining the patient's plan of care? (Select all that apply.) a) Ask the patient about the acceptable level of pain b) Eliminate all activities that precipitate the pain c) Administer the pain medications regularly around the clock d) Use a different pain scale each time to promote patient education e) Assess the patient's pain every 20 minutes

A, C Rationale: The nurse works together with the patient to determine the tolerable level of pain. Considering that the patient has chronic, not acute pain, the goal of pain management is to decrease pain to a tolerable level instead of eliminating pain completely.

What physiological factor(s) alters the pharmacokinetic properties of medication in the breast-feeding neonate? (Select all that apply.) a) Decreased fat content b) Increased protein binding c) Immature blood-brain barrier d) Increased first pass elimination e) Decreased glomerular filtration rate f) All The Above

A, C, E Rationale: In neonates, the fat content is low because of a large amount of total body water. As a result, the medication readily enters the bran because of the neonates' immature blood-brain barrier. Neonates have immature kidneys; therefore the glomerular filtration rate is decreased.

Risk factors for osteoarthritis include ________ (Select all that apply.) a) Older age b) Chronic carpel tunnel syndrome c) Genetics d) Being male e) Obesity

A, C, E Rationale: Osteoarthritis is more common with aging due to the cumulative effects of wear and tear on the joints over time. Individuals with a family history of Osteoarthritis are more susceptible for developing the condition. Excess body weight places increased stress on weight-bearing joints.

Which factors are unique to delirium when distinguishing between dementia and delirium? (Select all that apply.) a) Slurred speech b) Lability of mood c) Long-term memory loss d) Visual or tactile hallucinations e) Insidious deterioration of cognition f) A fluctuating level of consciousness

A, D, F Rationale: Delirium results in sparse or rapid speech that may be slurred/incoherent. Visual or tactile hallucinations/illusions may occur with delirium because of altered cerebral function. Patients w.ith delirium fluctuate from hyperalert to difficult to arouse; they may lost orientation to time and place.

What is the difference between evisceration and dehiscence? a) Evisceration is the separation of wound edges, while dehiscence involves protrusion of organs b) Dehiscence is the separation of wound edges and evisceration is the protrusion of organs c) Evisceration and dehiscence both refer to the same surgical complication d) Evisceration involves the incomplete closure of a wound, while dehiscence is the displacement of internal organs

B

Which action is the function of Antidiuretic Hormone (ADH)? a) Reduces blood volume b) Decreases water loss in urine c) Increases urine output d) Initiates the thirst mechanism

B Rationale: ADH is released mainly in response to a decrease in blood volume or an increased concentration of sodium or other substances in the plasma. ADH acts to decrease the production of urine by increasing the reabsorption of water by renal tubules.

What distinguishes acute pain from chronic pain? a) Chronic pain typically has a sudden onset, while acute pain develops gradually b) Acute pain is short-lived and decreases with healing, chronic pain persists and serves no useful purpose c) Acute pain is generally more severe than chronic pain d) Chronic pain is always associated with an identifiable injury or illness whereas acute pain is not

B Rationale: Acute pain is typically a response to a specific injury, illness or tissue damage and decreases as the injury heals. Chronic pain persists over an extended period, often beyond the expected time for healing, and does not serve a clear protective function

Which intravenous (IV) solution would the nurse anticipate administering when caring for a patient with a history of severe diarrhea for the past 3 days who is admitted for dehydration? a) 3% sodium chloride b) 0.9% sodium chloride c) 5% dextrose and lactated ringer solution d) 5% dextrose and 0.9% sodium chloride

B Rationale: An IV solution of 0.9% sodium chloride is the most appropriate initial IV fluid for this patient because it is an isotonic solution that will act as a volume expander to quickly replace volume losses.

A patient has been robbed, beaten, and sexually assaulted. The primary health care provider prescribed 0.25mg of alprazolam for agitation. Which event would alert the nurse to administer this medication? a) The patient's crying increases b) The patient requests something to calm her c) The nurse determines a need to reduce her anxiety d) The primary health care provider is getting ready to perform a vaginal examination
