Correct Answer: B

Rationale: Abdominal cramping is a common manifestation of hyponatremia, as the sodium imbalance affects muscle function. Numbness of the extremities (Choice A) is more commonly associated with electrolyte imbalances such as hypocalcemia. Bradycardia (Choice C) is not typically a direct manifestation of hyponatremia. Positive Chvostek's sign (Choice D) is related to hypocalcemia, not hyponatremia.

Correct Answer: B

Rationale: The correct answer is B. Nursing the baby frequently helps prevent engorgement and discomfort in breastfeeding mothers. Choice A is incorrect because tight-fitting bras can lead to clogged milk ducts and worsen discomfort. Choice C may lead to oversupply issues and is not necessary unless there is a specific indication. Choice D is incorrect as avoiding nursing for extended periods can lead to engorgement and decreased milk supply.

Correct Answer: A

Rationale: Correctly assessing a patient with potential pneumonia involves listening to lung sounds and monitoring oxygen saturation. Lung sounds can reveal abnormal breath sounds associated with pneumonia, such as crackles or diminished breath sounds. Oxygen saturation monitoring helps in detecting respiratory distress, a common complication of pneumonia. Monitoring for fever and sputum production (Choice B) is important but not as specific as assessing lung sounds and oxygen saturation. Auscultating heart sounds and checking for cyanosis (Choice C) are not primary assessments for pneumonia. Monitoring for chest pain and administering oxygen (Choice D) are relevant interventions but do not address the initial assessment of pneumonia.

Correct Answer: B

Rationale: The correct answer is B. A blood glucose level of 200 mg/dL indicates hyperglycemia, which may necessitate insulin adjustment to better control the client's blood sugar levels. A fasting blood glucose of 90 mg/dL (choice A) is within the normal range, a hemoglobin A1c of 6% (choice C) is indicative of good long-term blood sugar control, and a fasting blood glucose of 100 mg/dL (choice D) is also within the normal range. Therefore, these findings do not require immediate reporting to the provider.

Correct Answer: A

Rationale: The correct answer is A: Increased respiratory rate and use of accessory muscles are key signs of respiratory distress. When a person is experiencing respiratory distress, their respiratory rate typically increases as the body tries to compensate for the inadequate oxygenation. Additionally, the use of accessory muscles indicates that the person is working harder to breathe. Choices B, C, and D are incorrect because they do not accurately represent the key signs of respiratory distress. A decreased respiratory rate, cyanosis, altered mental status, and bradycardia are not typical signs of respiratory distress.
