Correct Answer: D

Rationale: A serum creatinine level of 3.0 mg/dL indicates impaired kidney function, which is a concern when prescribing spironolactone as it can further affect renal function. Elevated serum creatinine levels may suggest decreased renal clearance of spironolactone, leading to potential toxicity. Potassium, calcium, and magnesium levels are within normal ranges and not directly related to spironolactone therapy. Therefore, the nurse should report the elevated serum creatinine level to the provider for further evaluation and possible dosage adjustment.

Correct Answer: B

Rationale: Swelling of the arm above the insertion site is concerning as it can indicate complications like thrombosis, which require immediate attention. Redness at the insertion site is common and expected in the initial stages. A bruised area around the insertion site may result from the insertion procedure and is usually not alarming unless it worsens or becomes larger. A temperature of 37.2°C (99°F) is within the normal range and is not directly related to PICC complications.

Correct Answer: A

Rationale: The correct answer is A. Clozapine can cause agranulocytosis, a serious condition that decreases the number of white blood cells. Reporting a sore throat is crucial as it could be a sign of infection. Choice B is incorrect because there is no specific interaction between clozapine and grapefruit juice. Choice C is incorrect because clozapine is usually taken without regard to meals. Choice D is incorrect as clozapine is generally taken without food to enhance absorption.

Correct Answer: C

Rationale: The correct answer is C: Provide the client with a stool softener. Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. Providing the client with a stool softener is essential to prevent straining during bowel movements, which could result in bleeding for clients with thrombocytopenia. Encouraging the client to floss daily (choice A) is unrelated to the management of thrombocytopenia. Removing fresh flowers (choice B) is more relevant for clients with a compromised immune system. Avoiding serving raw vegetables (choice D) is important for clients with compromised immune systems to prevent foodborne illnesses, but it is not directly related to thrombocytopenia.

Correct Answer: A

Rationale: The correct method for measuring an infant's temperature is by placing the tip of the thermometer under the center of the infant's axilla (armpit). This method is non-invasive and safe. Pulling the pinna of the ear forward is used when taking a tympanic temperature. Inserting the probe into the rectum is done for rectal temperature measurement, which is not recommended as an initial method in infants. Inserting the thermometer in front of the infant's tongue is not a standard method for measuring temperature in infants.
