Correct Answer: B

Rationale: The correct lifestyle change that should be emphasized for a client with hypertension is to limit the intake of high-fat foods. High-fat foods can contribute to high blood pressure, so reducing their consumption is important in managing hypertension. Choice A is incorrect because increasing intake of sodium-rich foods can worsen hypertension due to their effect on blood pressure. Choice C is incorrect as caffeinated beverages can also elevate blood pressure. Choice D is incorrect because while high-protein foods can be beneficial, they do not directly lower blood pressure like reducing high-fat foods would.

Correct Answer: D

Rationale: In cases of magnesium sulfate toxicity, calcium gluconate is the antidote that should be administered promptly. Positioning the client supine (Choice A) is not the priority in this scenario. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Methylergonovine IM (Choice C) is used for postpartum hemorrhage, not for magnesium sulfate toxicity.

Correct Answer: D

Rationale: The correct answer is 'Difficulty urinating.' This finding is crucial to report promptly as it can indicate a complication, such as urinary retention or injury to the urinary tract, which are significant concerns post-hernia surgery. High blood pressure (Choice A) may require monitoring but is not as urgent as difficulty urinating. Decreased bowel sounds (Choice B) and constipation (Choice C) are common after surgery and may resolve with appropriate interventions but are not as critical as addressing difficulty urinating.

Correct Answer: B

Rationale: Performing a wound culture before applying antibiotics is crucial to identify the specific pathogen causing the infection. This helps in selecting the most effective antibiotics for treatment. Changing the wound dressing, applying a wet-to-dry dressing, or cleansing the wound are important interventions but should follow the assessment and identification of the infecting organism through a wound culture to guide appropriate treatment.

Correct Answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.
