A nurse is caring for a client that is newly diagnosed with hypertension.
The client noted that the provider will prescribe a medication to treat angina and hypertension.
Which of the following medications should the nurse expect the provider to prescribe?
Nifedipine.
Digoxin.
Heparin.
Captopril.
The Correct Answer is A
Choice A rationale
Nifedipine is a calcium channel blocker that is effective in treating hypertension and angina. It works by relaxing the blood vessels, which lowers blood pressure and improves blood flow to the heart, reducing chest pain and hypertension.
Choice B rationale
Digoxin is not typically used to treat hypertension. It is primarily used for heart failure and atrial fibrillation to increase the strength of heart muscle contractions and regulate heart rhythm.
Choice C rationale
Heparin is an anticoagulant used to prevent and treat blood clots. It does not directly treat hypertension or angina and is used for conditions like deep vein thrombosis, pulmonary embolism, and during surgeries to prevent clot formation.
Choice D rationale
Captopril is an ACE inhibitor used to treat hypertension and heart failure. While it is effective for lowering blood pressure, it is not primarily used for treating angina compared to medications like nifedipine or other calcium channel blockers.

Correct Answer is A
Explanation
Choice A rationale
Lactated Ringers (LR) is an isotonic solution, which means it has the same osmolarity as blood plasma. This property makes LR suitable for rehydrating patients without causing a significant shift of fluids between compartments, maintaining the balance of electrolytes.
Choice B rationale
0.45% Sodium Chloride is a hypotonic solution, meaning it has a lower osmolarity compared to blood plasma. This type of solution would cause fluid to move into cells, potentially leading to cellular swelling.
Choice C rationale
Dextrose in Lactated Ringers is a hypertonic solution because the added dextrose increases the osmolarity. This solution can cause fluid to shift out of cells, leading to cellular shrinkage, which is not ideal for rehydration.
Choice D rationale
None of the above is incorrect because Lactated Ringers (LR) is indeed an isotonic solution.
Correct Answer is A
Explanation
Choice A rationale
Beclomethasone (QVAR) is an inhaled corticosteroid used for long-term prophylaxis of asthma. It works by reducing inflammation in the airways, preventing asthma attacks and improving lung function.
Choice B rationale
Metoprolol is a beta-adrenergic blocker used for treating hypertension and certain heart conditions. It is not used for asthma management.
Choice C rationale
Phenytoin is an antiepileptic medication used to control seizures. It does not have a role in asthma management.
Choice D rationale
Furosemide is a loop diuretic used to treat conditions like edema and hypertension by promoting the excretion of excess fluid. It is not indicated for asthma management.
