A 43-year-old woman with a history of hypertension drinks one to two cups of coffee per day. She has been doing this for 3 months. As a result of her continued behavior, which of the following effects of coffee is most likely for her?

Correct Answer: C

Rationale: Daily coffee (caffeine) for 3 months likely leads to tolerance . Regular use reduces adenosine blockade's stimulant effect. Fatigue decrease and alertness wane with tolerance. Tremors and withdrawal (E) need higher doses or cessation. Tolerance fits her chronic intake.

Correct Answer: D

Rationale: Weight loss, tachycardia, and goitre suggest hyperthyroidism (e.g., Graves'). Verapamil controls rate but not thyroid function. Radioactive iodine (131I) treats long-term, not immediately. Carbamazepine is for seizures, L-thyroxine worsens hyperthyroidism. Atenolol, a beta-blocker, immediately reduces tachycardia and symptoms by blocking adrenergic effects, suitable for acute management while awaiting antithyroid drugs (e.g., propylthiouracil). Its symptomatic relief is critical in hyperthyroid crises.

Correct Answer: A

Rationale: Furosemide belongs to the class of drugs known as loop diuretics. These diuretics act on the thick ascending loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased urine production and subsequent fluid loss. Loop diuretics are commonly used to treat conditions such as heart failure, hypertension, and edema. Furosemide is a widely prescribed loop diuretic known for its potent diuretic effects.

Correct Answer: A

Rationale: When a patient taking high-dose aspirin for arthritis requires prednisone for an acute flare, the nurse should be aware that prednisone can increase blood glucose levels. As such, the nurse should monitor the patient for signs and symptoms of hyperglycemia, not hypoglycemia. It is essential to closely monitor the patient's blood glucose levels to prevent complications associated with high blood sugar levels, such as hyperglycemia. It is also crucial to educate the patient about the potential side effects of prednisone and instruct the patient on how to manage blood glucose levels while taking the medication.

Correct Answer: D

Rationale: Nystatin treats infant thrush, often linked to maternal Candida transmission during breastfeeding. The key instruction 'The breastfeeding mother may also require treatment' prevents reinfection (correct answers: 3, 5), addressing the cycle comprehensively. Before feeding reduces efficacy as milk washes it away. Water dilutes the dose unnecessarily. Cotton swab application ensures coverage but isn't the priority over maternal treatment. Choice D ensures long-term success, critical for caregiver education and infection control.
