A client presents to the healthcare setting after beginning treatment with an Angiotensin Converting Enzyme (ACE) inhibitor. Which of the following side- effects will the nurse be sure to assess for?
Dry, non-productive cough
Nausea and vomiting
Hypokalemia and vomiting
Epistaxis and headache
The Correct Answer is A
A) Dry, non-productive cough: One of the most common side effects associated with ACE inhibitors is a dry, non-productive cough. This occurs due to the accumulation of bradykinin, a peptide that can increase in the body when ACE is inhibited. Nurses should assess for this symptom, as it may require changing the medication if it becomes bothersome to the client.
B) Nausea and vomiting: While nausea and vomiting can occur with various medications, they are not specific or common side effects of ACE inhibitors. If these symptoms do arise, they may be due to other factors and should be investigated further.
C) Hypokalemia and vomiting: ACE inhibitors are more commonly associated with hyperkalemia (elevated potassium levels) rather than hypokalemia. Monitoring potassium levels is important, but vomiting is not a typical side effect of ACE inhibitors.
D) Epistaxis and headache: Although headaches can occur with many medications, epistaxis (nosebleeds) is not a common side effect associated with ACE inhibitors. While headache assessment is appropriate, the dry cough is the more characteristic and important symptom to monitor in clients on these medications.

Correct Answer is A
Explanation
A) Hypokalemia: Hypokalemia, or low potassium levels, significantly increases the risk of digoxin toxicity. Since digoxin competes with potassium for binding at the sodium-potassium ATPase site in the heart, low potassium levels can lead to increased digoxin effects and toxicity. Therefore, it is crucial to monitor potassium levels and correct any deficiencies before administering digoxin.
B) Hyperkalemia: While hyperkalemia is a serious concern and can also affect digoxin therapy, it usually results in decreased effectiveness of digoxin rather than increasing toxicity. Elevated potassium levels can diminish the drug's positive inotropic effect.
C) Hypocalcemia: Although calcium levels can influence cardiac function, hypocalcemia is not directly related to digoxin toxicity. Monitoring calcium is important for overall cardiac health, but it is not the primary focus when assessing the risk for digoxin toxicity.
D) Hypernatremia: Elevated sodium levels do not have a direct impact on the efficacy or toxicity of digoxin. While sodium levels are essential to monitor for overall health, they are not critical in the context of digoxin administration and toxicity risk.
Correct Answer is C
Explanation
A) "Acts on the beta cells within the heart and lungs to regulate cardiac rhythm.": This statement is incorrect because calcium channel blockers do not primarily act on beta cells. Instead, they block calcium channels in cardiac and smooth muscle, which affects heart contractility and conductivity.
B) "Increases heart rate and increases myocardial contractility.": Calcium channel blockers typically do the opposite; they decrease heart rate and myocardial contractility by inhibiting calcium entry into the heart muscle cells. Therefore, this statement does not accurately describe their mechanism of action.
C) "Reduces the contractility and conductivity of the heart.": This statement accurately reflects the action of calcium channel blockers. By blocking calcium entry, these medications decrease myocardial contractility and slow down electrical conduction through the heart, which can help manage dysrhythmias.
D) "Increase oxygen to the systemic circulation.": While calcium channel blockers can improve blood flow and reduce myocardial oxygen demand by decreasing heart workload, their primary action does not directly focus on increasing oxygen delivery to systemic circulation. Their primary role is in managing heart contractility and rhythm.
