Correct Answer: C

Rationale: The correct action for the nurse to take while caring for a newborn with jaundice receiving phototherapy is to ensure that the newborn wears a diaper. This is essential to prevent skin irritation during phototherapy. Feeding the infant glucose water or applying lotion are not pertinent to managing jaundice or phototherapy. Keeping the infant's head covered with a cap is also not necessary for this specific situation.

Correct Answer: C

Rationale: The correct answer is C: 'Take medications at the same time every day.' Consistency in medication administration is crucial for stroke recovery to maintain therapeutic drug levels in the body. Choice A, 'Avoid lifting more than 5 pounds,' though important to prevent strain, is not directly related to medication adherence. Choice B, 'Perform range-of-motion exercises daily,' is beneficial for overall recovery but is not specific to medication management. Choice D, 'Monitor blood pressure daily,' is important but does not address the key aspect of medication regimen adherence.

Correct Answer: C

Rationale: During an acute asthma exacerbation, the priority is to quickly relieve bronchoconstriction and improve airflow. Albuterol is a short-acting bronchodilator that acts rapidly to dilate the airways, making it the first-line medication for acute symptom relief. Montelukast is a leukotriene receptor antagonist used for long-term asthma control, not for immediate relief. Salmeterol is a long-acting bronchodilator used for maintenance therapy, not for acute exacerbations. Fluticasone is an inhaled corticosteroid that reduces airway inflammation and is also used for long-term control, not for immediate relief during an exacerbation.

Correct Answer: D

Rationale: The correct answer is D. Black, tarry stools can indicate gastrointestinal bleeding, a serious adverse effect of warfarin that requires immediate medical attention. Option A is incorrect because while bruising is a common side effect of warfarin, it is not limited to the elbows. Option B is incorrect as a red rash is not a typical adverse effect of warfarin. Option C is also incorrect because developing a cough is not a reason to discontinue warfarin unless advised by a healthcare provider.

Correct Answer: C

Rationale: The correct answer is C. Monitoring blood glucose levels before meals and at bedtime is crucial for managing type 2 diabetes mellitus. Option A is incorrect because limiting protein intake is not a primary focus for diabetes management. Option B is unrelated to diabetes management and focuses on pain relief. Option D mentions reducing carbohydrate intake, which is a common dietary recommendation for managing blood sugar levels, but it is not as specific as monitoring blood glucose levels at key times.
