Correct Answer: C

Rationale: The correct answer is C. Pacing spikes after the QRS complex indicate a malfunction of the pacemaker and should be reported. Choice A is not directly related to the pacemaker function. Choice B, hiccups, are common and not typically associated with pacemaker issues. Choice D, a heart rate of 90 beats per minute, is within the normal range and does not indicate a pacemaker malfunction.

Correct Answer: C

Rationale: The correct answer is C: "Avoid drinking more than 1 liter of fluid per day." Clients with heart failure are typically advised to limit their fluid intake to around 1 liter per day to prevent fluid overload, which can worsen their condition. Choices A, B, and D are incorrect because they suggest fluid intakes that are higher than the recommended limit, which could lead to fluid retention and exacerbate heart failure symptoms.

Correct Answer: A

Rationale: The correct answer is A: 'I will avoid crowded places to reduce my risk of infection.' When taking prednisone, clients should avoid crowded places to reduce the risk of infection due to its immunosuppressive effects. Choice B is incorrect because prednisone is usually taken with food to reduce stomach upset. Choice C is incorrect because clients should not stop taking prednisone abruptly, even if they experience nausea. Choice D is incorrect because prednisone should be tapered off gradually under healthcare provider guidance instead of being stopped abruptly after 2 weeks.

Correct Answer: D

Rationale: The correct answer is D, oatmeal. Oatmeal contains insoluble fiber, which can exacerbate the symptoms of irritable bowel syndrome. Choices A, B, and C are not typically problematic for individuals with IBS. Lean cuts of pork, low-fat yogurt, and white bread are generally well-tolerated and may even be recommended as part of a balanced diet for individuals with IBS.

Correct Answer: C

Rationale: The correct answer is to provide the client with a stool softener. Thrombocytopenia is a condition characterized by a low platelet count, leading to decreased blood clotting ability. Providing a stool softener is essential to prevent constipation and straining during bowel movements, which can lead to bleeding in thrombocytopenic clients. Encouraging the client to floss daily (Choice A) is a good oral hygiene practice but is not directly related to managing thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is important for immunocompromised clients to prevent exposure to pathogens but is not specifically related to thrombocytopenia. Avoiding serving raw vegetables (Choice D) is a precaution to reduce the risk of infection in immunocompromised clients but does not directly address the complications of thrombocytopenia.
