Correct Answer: B

Rationale: Corrected Rationale: Assessing cardiac status is crucial in hyperkalemia as high potassium levels can result in life-threatening arrhythmias. Monitoring the heart rhythm and ECG findings is essential to prevent cardiac complications. Neurological status, respiratory status, and gastrointestinal status are important assessments too, but in the context of hyperkalemia, cardiac status takes precedence due to the immediate risk of cardiac arrhythmias.

Correct Answer: C

Rationale: The correct answer is C because bran cereal is a high-fiber food that can effectively alleviate constipation by promoting regular bowel movements. Option A, an apple, while a healthy snack, may not provide as much fiber as bran cereal. Option B, sweet potatoes, are nutritious but may not be as high in fiber as bran cereal. Option D, almonds, are a good source of healthy fats and protein but do not provide as much fiber as bran cereal.

Correct Answer: A

Rationale: The correct answer is A: S3 ventricular gallop. An S3 sound is a common finding in congestive heart failure due to fluid overload in the heart. It is associated with decreased ventricular compliance. Choices B, C, and D are incorrect. An apical click is not typically associated with congestive heart failure. A systolic murmur may be heard in conditions like mitral regurgitation but is not specific to congestive heart failure. A split S2 is associated with conditions like pulmonary hypertension, not congestive heart failure.

Correct Answer: C

Rationale: The correct answer is C. Eating crackers before getting out of bed can help manage nausea associated with hyperemesis gravidarum. Choice A is incorrect because drinking water with meals may exacerbate nausea. Choice B is incorrect as eating every 6 hours may not be frequent enough to combat nausea and vomiting. Choice D is incorrect because protein intake should not be limited during pregnancy, especially in cases of hyperemesis gravidarum.

Correct Answer: C

Rationale: Keeping conversations short is the most appropriate intervention to promote comfort for a client with pneumonia. Pneumonia can be physically exhausting, and limiting the length of conversations helps conserve the client's energy. Encouraging visits from family and friends (Choice B) may be emotionally supportive but might not directly promote comfort in the context of conserving energy during recovery. Increasing oral fluid intake (Choice A) is important for hydration but may not directly address the client's comfort. Monitoring vital signs frequently (Choice D) is essential for assessing the client's condition but does not directly promote comfort.
