1. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?

A. Cardiac output.
B. Right atrial blood flow.
C. Left end-diastolic pressure.
D. Cardiac index.

Correct answer: C

Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.

2. 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).

3. The client has been receiving peritoneal dialysis. The nurse should assess the client for which of the following complications that is most likely to occur?

A. Electrolyte imbalance
B. Peritonitis
C. Infection
D. Hyperglycemia

Correct answer: B

Rationale: Peritonitis is the most likely complication to occur in clients receiving peritoneal dialysis due to the risk of infection. Peritonitis is a serious inflammation of the peritoneum lining the abdominal cavity, commonly caused by infection. While electrolyte imbalance and hyperglycemia are possible complications in some cases, peritonitis poses a more immediate and severe threat to the client's health. Infection is a general term that can encompass peritonitis but is not as specific as directly identifying peritonitis as the primary concern in this scenario.

4. A client who has received sodium bicarbonate in large amounts is at risk for metabolic alkalosis. For which of the following signs and symptoms does the nurse assess this client?

A. Disorientation and dyspnea
B. Drowsiness, headache, and tachypnea
C. Tachypnea, dizziness, and paresthesias
D. Dysrhythmias and decreased respiratory rate and depth

Correct answer: D

Rationale: The correct answer is D. A client with metabolic alkalosis may present with dysrhythmias and a decreased respiratory rate and depth as the body tries to compensate by retaining carbon dioxide. Options A, B, and C do not typically correlate with the signs and symptoms of metabolic alkalosis. Disorientation, dyspnea, drowsiness, headache, tachypnea, dizziness, and paresthesias are not commonly associated with metabolic alkalosis. Therefore, they are incorrect choices.

5. Which of the following medications is commonly prescribed for hypertension?

A. Atenolol
B. Aspirin
C. Ibuprofen
D. Metformin

Correct answer: A

Rationale: The correct answer is Atenolol. Atenolol is a beta-blocker commonly prescribed to manage hypertension due to its ability to reduce the heart rate and lower blood pressure. Options B, C, and D are incorrect because aspirin, ibuprofen, and metformin are not typically used as first-line treatments for hypertension. Aspirin is more commonly used for its antiplatelet effects, ibuprofen is a nonsteroidal anti-inflammatory drug, and metformin is primarily used for managing diabetes.
