he nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin (Lanoxin)?

hypokalemia

hyperkalemia

hypocalcemia

hypernatremia

Answer and Explanation

The Correct Answer is A

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.

A. "Depending on the level of your PT/INR, the clot will begin to dissolve." B. "After the first dose, the clot will begin to dissolve." C. "It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level." D. "Heparin does not dissolve clots. It stops new clots from forming."

Correct Answer is D

Explanation

A. "Depending on the level of your PT/INR, the clot will begin to dissolve.": This response is misleading, as heparin's effect is not primarily monitored by PT/INR; rather, heparin is monitored by activated partial thromboplastin time (aPTT). Moreover, heparin does not directly dissolve clots; it prevents further clot formation.

B. "After the first dose, the clot will begin to dissolve.": This statement inaccurately suggests that heparin has an immediate effect on dissolving existing clots. While heparin acts quickly to inhibit further clotting, it does not lead to the dissolution of clots after the first dose.

C. "It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.": This is not accurate for heparin, which has an immediate effect on coagulation. While the therapeutic effects can be optimized over several days, heparin begins to work right away to prevent further clotting.

D. "Heparin does not dissolve clots. It stops new clots from forming.": This response accurately describes the mechanism of action of heparin. Heparin prevents the extension of existing clots and the formation of new clots, but it does not actively dissolve clots. This clarification is essential for the client’s understanding of their treatment and expectations regarding DVT management.

A. angioedema B. dry non-productive cough C. hyperkalemia D. first dose phenomenon E. hypotension F. Hypertension

Correct Answer is ["A","B","C","D","E"]

Explanation

A) Angioedema: Quinapril, an ACE inhibitor, can cause angioedema, which is a serious allergic reaction characterized by swelling of the deeper layers of the skin. This side effect is critical to monitor, as it can lead to airway obstruction.

B) Dry non-productive cough: A persistent dry cough is a well-known side effect of ACE inhibitors like quinapril. This occurs due to the accumulation of bradykinin and can be bothersome enough to require discontinuation of the medication.

C) Hyperkalemia: Quinapril can lead to increased potassium levels in the blood, a condition known as hyperkalemia. This is due to the drug's mechanism of action, which reduces aldosterone secretion, leading to decreased potassium excretion.

D) First dose phenomenon: This refers to a significant drop in blood pressure following the first dose of an ACE inhibitor, which can lead to dizziness or fainting. Patients are often advised to take the first dose at bedtime to minimize this risk.

E) Hypotension: Quinapril can cause hypotension, particularly after the initial dosing or in patients who are dehydrated or on diuretics. It’s important for patients to be aware of this potential side effect.

F) Hypertension: Quinapril is used to treat hypertension, so it is not a side effect associated with this medication. Instead, the goal of treatment is to lower blood pressure, making this option incorrect.
