Correct Answer: B

Rationale: The correct answer is B: Pericardial friction rub. This is a key diagnostic sign of pericarditis due to the inflammation of the pericardial layers causing a rough, grating sound heard upon auscultation. Precordial pain (A) is a common symptom but not a specific diagnostic sign. Hypotension (C) and rapid/labored respirations (D) are not typically associated with pericarditis. Therefore, the presence of a pericardial friction rub is crucial in confirming the diagnosis of pericarditis.

Correct Answer: B

Rationale: The correct answer is B: Fluid retention and weight gain. Prednisone is a corticosteroid that can cause fluid retention and weight gain as common adverse reactions. Here's the rationale: Prednisone is known to increase sodium and water retention in the body, leading to fluid retention and subsequent weight gain. This occurs due to the drug's impact on the body's electrolyte balance. Tetany and tremors (Choice A) are not common adverse reactions associated with prednisone use. Anorexia and weight loss (Choice C) are also not typical reactions, as prednisone is more likely to cause weight gain. Choice D, "None of the above," is incorrect as prednisone commonly causes fluid retention and weight gain as adverse reactions.

Correct Answer: B

Rationale: The correct answer is B: Hemorrhage. The nurse manager would intervene because hemorrhage is a life-threatening condition requiring immediate attention. Wandering (A), urinary retention (C), and impaired swallowing (D) are important assessments but do not pose the same level of immediate risk as hemorrhage. The nurse manager would prioritize addressing the hemorrhage to ensure the patient's safety and well-being.

Correct Answer: B

Rationale: The correct answer is B: Take the NSAID with meals. Taking NSAIDs with meals helps reduce stomach irritation and risk of developing ulcers. Food acts as a protective barrier and helps in the absorption of the medication. Incorrect Choices: A: Taking NSAID with aspirin can increase the risk of stomach irritation and bleeding due to combined antiplatelet effects. C: Orange juice does not potentiate the effect of NSAIDs and may even worsen stomach irritation due to its acidity. D: NSAIDs do not coat the stomach lining; in fact, they can irritate the stomach lining and increase the risk of ulcers.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Providing oral care does not directly address fluid balance or hydration status. 2. Oral care focuses on maintaining oral hygiene and preventing infections. 3. Choices A, B, and D all involve fluid intake to address dehydration. 4. Offering large amounts of fluid, enteral or parenteral fluids, and small volumes at frequent intervals all aim to correct the patient's condition by replenishing lost fluids. Summary: Choice C is incorrect because oral care does not directly address the patient's dehydration. Choices A, B, and D are better options as they focus on fluid replacement to correct the patient's condition.
