1. The client with diabetes mellitus should be cautioned by the nurse taking a sulfonylurea that alcoholic beverages should be avoided while taking these drugs because they can cause which of the following?
- A. Hypokalemia.
- B. Hyperkalemia.
- C. Hypocalcemia.
- D. Disulfiram (Antabuse)-like symptoms.
Correct answer: D
Rationale: The correct answer is D: Disulfiram (Antabuse)-like symptoms. When a client with diabetes mellitus taking a sulfonylurea consumes alcohol, it can lead to disulfiram-like symptoms, such as nausea, flushing, and palpitations. Choice A, hypokalemia, is incorrect because sulfonylureas do not typically lead to low potassium levels. Choice B, hyperkalemia, is incorrect as sulfonylureas are not associated with high potassium levels. Choice C, hypocalcemia, is also incorrect because sulfonylureas are not known to cause low calcium levels.
2. What is the primary purpose of administering IV fluids to a patient in septic shock?
- A. To reduce blood pressure.
- B. To increase cardiac output.
- C. To stabilize blood glucose levels.
- D. To maintain adequate tissue perfusion.
Correct answer: D
Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.
3. During an assessment on a patient brought to the emergency department for treatment for dehydration, the nurse notes a respiratory rate of 26 breaths/minute, a heart rate of 110 beats/minute, a blood pressure of 86/50 mm Hg, and a temperature of 39.5° C. The patient becomes dizzy when transferred from the wheelchair to a bed. The nurse observes cool, clammy skin. Which diagnosis does the nurse suspect?
- A. Fluid volume deficit (FVD)
- B. Fluid volume excess (FVE)
- C. Mild extracellular fluid (ECF) deficit
- D. Renal failure
Correct answer: A
Rationale: The nurse should suspect Fluid Volume Deficit (FVD) in this patient. Signs of FVD include elevated temperature, tachycardia, tachypnea, hypotension, orthostatic hypotension, and cool, clammy skin, which align with the patient's assessment findings. Choices B, C, and D are incorrect. Fluid Volume Excess (FVE) typically presents with bounding pulses, elevated blood pressure, dyspnea, and crackles. Mild extracellular fluid (ECF) deficit usually manifests as thirst. Renal failure commonly results in Fluid Volume Excess (FVE) rather than Fluid Volume Deficit (FVD).
4. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, 'The client will verbalize symptoms of pacemaker failure.' Which symptoms are most important to teach the client?
- A. Facial flushing.
- B. Fever.
- C. Pounding headache.
- D. Feelings of dizziness.
Correct answer: D
Rationale: The correct answer is 'D: Feelings of dizziness.' Feelings of dizziness may occur as a result of a decreased heart rate, leading to decreased cardiac output, which can be an indication of pacemaker failure. Teaching the client to recognize symptoms of decreased cardiac output, like dizziness, is crucial for early detection of pacemaker malfunction. Choices A, B, and C are less specific to pacemaker failure and are not commonly associated with this condition. Facial flushing, fever, and pounding headache are not typical signs of pacemaker failure and are not directly related to cardiac output, making them less relevant for teaching the client about pacemaker failure.
5. The patient will take a high dose of azithromycin after discharge from the hospital. Which statement by the patient indicates understanding of the teaching?
- A. I may take antacids 2 hours before taking this drug.
- B. I should take acetaminophen for fever or mild pain.
- C. I should expect diarrhea to be a common, mild side effect.
- D. I should avoid dairy products while taking this drug.
Correct answer: A
Rationale: The correct answer is A. Azithromycin peak levels may be reduced by antacids when taken at the same time, so patients should be cautioned to take antacids 2 hours before or 2 hours after taking the drug. Choice B is incorrect because high-dose azithromycin carries a risk for hepatotoxicity when taken with other potentially hepatotoxic drugs such as acetaminophen. Choice C is incorrect as diarrhea may indicate pseudomembranous colitis and should be reported, not expected as a common mild side effect. Choice D is incorrect; there is no restriction for dairy products while taking azithromycin.
