Correct Answer: B

Rationale: A serum potassium level of 3.2 mEq/L is low (hypokalemia), which can be concerning in a patient with cirrhosis who is already at risk for electrolyte imbalances. Spironolactone is a potassium-sparing diuretic that can help increase the patient's potassium level and correct the hypokalemia. Therefore, the appropriate action for the nurse to take in this scenario is to administer the spironolactone. Withholding the spironolactone could further lower the potassium level. Furosemide, on the other hand, is a loop diuretic that can lead to potassium loss and worsen hypokalemia; hence, it should be withheld until the nurse discusses the situation with the healthcare provider. While the healthcare provider should be informed about the low potassium value, immediate administration of spironolactone is necessary to address the hypokalemia in this patient population.

Correct Answer: C

Rationale: To palpate the liver effectively during a head-to-toe physical assessment, the patient should be positioned on the right side with the bed flat. This position helps to splint the biopsy site and allows for proper palpation of the liver. Elevating the head of the bed has no direct relevance to palpating the liver. Checking coagulation studies is done before the biopsy and is unrelated to palpation. Putting pressure on the biopsy site using a sandbag is not an appropriate way to facilitate liver palpation as it does not provide the necessary support and stabilization needed for the procedure.

Correct Answer: A

Rationale: The priority intervention in this scenario is to start a large-bore IV in the patient's arm. The patient's low blood pressure (95/60) and elevated pulse rate (110 beats per minute) indicate a potential hemorrhage, requiring immediate fluid resuscitation. Starting a large-bore IV will allow for rapid administration of fluids to stabilize the patient's condition. Asking for a stool sample, preparing to insert an NG tube, or administering morphine sulfate should not take precedence over addressing the hemodynamic instability and potential hemorrhage observed in the patient. These actions may be considered later in the patient's care, but the primary focus should be on addressing the critical issue of fluid replacement and stabilization.

Correct Answer: D

Rationale: The critical finding that should be reported immediately to the healthcare provider is 'No measurable voiding in 4 hours.' This finding raises concerns about possible hyperkalemia, which can result from continued potassium administration and a decrease in urinary output. Hyperkalemia can lead to serious complications, including cardiac arrhythmias. The management of acute hyperkalemia involves interventions such as administering calcium to protect the heart, shifting potassium into cells, and enhancing potassium elimination from the body. The other choices do not indicate an urgent issue that requires immediate attention. Three episodes of vomiting in 1 hour can be concerning but may not be as immediately critical as the risk of hyperkalemia. Periodic crying and irritability are common in infants and may not indicate a severe complication. Vigorous sucking on a pacifier is a normal behavior in infants and does not signal a medical emergency.

Correct Answer: B

Rationale: The correct answer is B: Pegylated α-interferon (PEG-Intron, Pegasys) SQ weekly. Pegylated α-interferon is typically administered once weekly, not daily. Therefore, this medication requires further discussion with the healthcare provider before administration to ensure the correct dosing frequency. Ribavirin, choice A, is appropriate for chronic hepatitis C treatment. Choices C and D, Diphenhydramine and Dimenhydrinate, are commonly used for symptomatic relief in patients with hepatitis C and do not require further discussion with the healthcare provider in this context.
