1. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?

A. Take this medication with food.
B. Take this medication at bedtime.
C. Take this medication on an empty stomach.
D. Take this medication with antacids.

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, affecting the medication's effectiveness.

2. Which of the following drugs is associated with hepatitis as a reaction?

A. Valproic acid
B. Quinidine
C. Isoniazid
D. Ethosuximide

Correct answer: C

Rationale: Hepatitis is a known side effect of isoniazid. It is important to monitor patients on isoniazid for signs of liver damage, including hepatitis, as part of their treatment regimen for tuberculosis.

3. A client has a new prescription for a Nitroglycerin transdermal patch for Angina Pectoris. Which of the following instructions should the nurse include?

A. Remove the patch each evening.
B. Do not cut the patch in half even if angina attacks are under control.
C. Take off the nitroglycerin patch if a headache occurs.
D. Apply a new patch every 48 hours.

Correct answer: A

Rationale: The correct instruction is to remove the nitroglycerin patch each evening to prevent tolerance. This allows for a 10- to 12-hour nitrate-free period daily, reducing the risk of developing tolerance to nitroglycerin. Cutting the patch in half is not recommended because it can alter the dosing and absorption rate, leading to inadequate symptom control. Taking off the patch for a headache is not necessary as headaches are a common side effect that may improve with continued use. Applying a new patch every 48 hours is not correct as it may not provide continuous symptom relief for angina.

4. The nurse is caring for a client who has chronic angina. Treatment for the condition has been unsuccessful. Which medication does the nurse anticipate will be prescribed?

A. Atenolol (Tenormin)
B. Nitroglycerin (Nitrostat)
C. Sildenafil (Viagra)
D. Ranolazine (Ranexa)

Correct answer: D

Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.

5. Which of the following is not a side effect of loop diuretics?

A. Alkalosis
B. Nausea
C. Hypotension
D. Potassium deficits

Correct answer: B

Rationale: Nausea is not commonly associated with loop diuretics. Loop diuretics are known to cause electrolyte imbalances such as potassium deficits, metabolic alkalosis, and hypotension due to excessive fluid loss. Nausea is not a typical side effect of loop diuretics.
