Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to reflect on their own thoughts and identify potential causes of their fatigue. It allows the patient to express their own insights and helps the nurse understand the underlying reasons for the fatigue. Choice A focuses on stress, which may not be the main cause of fatigue. Choice C is irrelevant to exploring the fatigue further. Choice D assumes that lack of sleep is the main issue, which may not be the case for the patient.

Correct Answer: A

Rationale: The correct answer is A because hyperparathyroidism is not caused by increased levels of thyroxine but by overactivity of the parathyroid glands. This would lead to symptoms of heat intolerance due to increased metabolism and systolic hypertension due to the effects of excess parathyroid hormone on calcium levels. Choice B is incorrect because diastolic hypertension and widened pulse pressure are not typical symptoms of hyperparathyroidism. Choice C is incorrect because weight gain is not a common symptom of hyperparathyroidism. Choice D is incorrect because anorexia and hyper-excitability are not typical symptoms of hyperparathyroidism.

Correct Answer: D

Rationale: Step 1: Hypernatremia is defined by elevated serum sodium levels (>145mEq/L). Step 2: Serum osmolality of 245mOsm/kg is high, consistent with hypernatremia. Step 3: Urine specific gravity below 1.003 indicates dilute urine, a common finding in hypernatremia. Step 4: The combination of elevated serum sodium, high serum osmolality, and low urine specific gravity confirms hypernatremia. Summary: A: Incorrect, as high serum osmolality (not 245mOsm/kg) is associated with hypernatremia. B: Incorrect, as low urine specific gravity (not below 1.003) is seen in hypernatremia. C: Incorrect, as serum sodium needs to be >145mEq/L to indicate hypernatremia.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Applying antibiotic ointment and placing the mother in reverse isolation are not appropriate for managing vesicles suspected to be herpes simplex virus (HSV) during labor. 2. HSV can be transmitted to the baby during vaginal delivery, leading to serious consequences. 3. Standard precautions should always be maintained to prevent the spread of infections. 4. Preparing for the possibility of a cesarean section and notifying the obstetrician about the vesicles are important steps to protect the baby and staff from potential harm.

Correct Answer: A

Rationale: The correct answer is A: Antiemetic. Chemotherapy commonly causes nausea and vomiting as adverse effects. Antiemetics are medications specifically designed to prevent or alleviate nausea and vomiting. Administering an antiemetic helps to manage these side effects and improve the patient's comfort and compliance with treatment. Antibiotics (choice B) are used to treat bacterial infections and are not directly related to combating chemotherapy side effects. Antimetabolites (choice C) are a type of chemotherapy drug, not used to combat its side effects. Anticoagulants (choice D) are used to prevent blood clots and are not indicated for managing chemotherapy-related nausea and vomiting.
