Which of the following interventions is most appropriate for a nurse to perform prior to administering Lasix to a client with heart failure?

Advise the client to avoid highfiber foods with the medication.

Encourage the client to consume a potassium rich diet.

Assess the client’s respiratory rate and oxygen saturation.

Instruct the client to increase fluid intake to prevent dehydration.

Answer and Explanation

The Correct Answer is C

Choice A reason: Advise the client to avoid highfiber foods with the medication is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix does not interact with highfiber foods or affect the digestion directly. Highfiber foods can actually help prevent or treat constipation, which can be a side effect of Lasix. The nurse should encourage the client to eat a balanced and nutritious diet, unless they have any dietary restrictions or allergies.

Choice B reason: Encourage the client to consume a potassium rich diet is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should monitor the serum potassium level and administer potassium supplements or potassiumsparing diuretics as prescribed to prevent hypokalemia. Consuming a potassium rich diet may not be sufficient or safe to correct the potassium imbalance caused by Lasix, especially in clients with kidney impairment or other medications that affect the potassium level.

Choice C reason: Assess the client’s respiratory rate and oxygen saturation is the most appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can help reduce the fluid overload and congestion in the lungs, which can cause shortness of breath, difficulty breathing, fatigue, and low oxygen levels in clients with heart failure. The nurse should assess the client’s respiratory rate and oxygen saturation to evaluate the severity of the pulmonary edema and the effectiveness of the Lasix therapy. The nurse should also monitor the client’s vital signs, fluid intake and output, and weight to ensure adequate fluid balance and hemodynamic stability.

Choice D reason: Instruct the client to increase fluid intake to prevent dehydration is not an appropriate intervention for a nurse to perform prior to administering Lasix to a client with heart failure. Lasix is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can cause dehydration, which can lead to symptoms such as thirst, dry mouth, dark urine, and fatigue. However, increasing fluid intake to prevent dehydration can worsen the fluid overload and congestion in the lungs, which can cause shortness of breath, difficulty breathing, fatigue, and low oxygen levels in clients with heart failure. The nurse should advise the client to drink enough fluids to maintain hydration, but not to exceed the prescribed fluid restriction, which is usually around 1.52 liters per day. The nurse should also educate the client about the signs and symptoms of dehydration and fluid overload, and when to seek medical attention.

Correct Answer is C

Explanation

Choice A reason: Vasodilation is not the primary therapeutic effect of atropine in this scenario. Atropine is a medication that blocks the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Atropine can cause vasodilation by inhibiting the muscarinic receptors on the blood vessels, which normally cause vasoconstriction. However, this effect is not significant or consistent, and it does not improve the symptoms of bradycardia, which is a slow heart rate that can cause dizziness, fatigue, or fainting. The nurse should monitor the blood pressure and the peripheral pulses of the patient after administering atropine.

Choice B reason: Bronchodilation is not the primary therapeutic effect of atropine in this scenario. Atropine is a medication that blocks the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Atropine can cause bronchodilation by inhibiting the muscarinic receptors on the bronchial smooth muscle, which normally cause bronchoconstriction. However, this effect is not relevant or beneficial for the patient with symptomatic bradycardia, who does not have any respiratory problems. The nurse should assess the respiratory rate and the breath sounds of the patient after administering atropine.

Choice C reason: Increase in heart rate is the primary therapeutic effect of atropine in this scenario. Atropine is a medication that blocks the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Atropine can increase the heart rate by inhibiting the muscarinic receptors on the sinoatrial node and the atrioventricular node, which normally slow down the heart rate. This effect is desirable and beneficial for the patient with symptomatic bradycardia, who has a slow heart rate that can cause dizziness, fatigue, or fainting. The nurse should monitor the electrocardiogram and the heart rate of the patient after administering atropine.

Choice D reason: Diuresis is not the primary therapeutic effect of atropine in this scenario. Atropine is a medication that blocks the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Atropine can cause diuresis by inhibiting the muscarinic receptors on the bladder, which normally promote urination. However, this effect is not important or helpful for the patient with symptomatic bradycardia, who does not have any urinary problems. The nurse should measure the urine output and the specific gravity of the patient after administering atropine.

A. Increased respiratory rate B. Bronchodilation C. Decreased sputum production D. Wheezing

Correct Answer is D

Explanation

Choice A reason: Increased respiratory rate is not a sign of adverse reaction to metoprolol, but rather a normal response to hypoxia or distress. Metoprolol is a betablocker that can lower the heart rate and blood pressure, but it does not affect the respiratory rate directly.

Choice B reason: Bronchodilation is not a sign of adverse reaction to metoprolol, but rather a desired effect of asthma medications such as betaagonists or anticholinergics. Metoprolol is a betablocker that can block the beta receptors in the lungs, which can cause bronchoconstriction or narrowing of the airways. This is why metoprolol is contraindicated or used with caution in clients with asthma.

Choice C reason: Decreased sputum production is not a sign of adverse reaction to metoprolol, but rather a result of effective asthma management. Metoprolol is a betablocker that does not have any direct effect on the mucus secretion or inflammation in the lungs.

Choice D reason: Wheezing is a sign of adverse reaction to metoprolol, as it indicates bronchoconstriction or narrowing of the airways. Metoprolol is a betablocker that can block the beta receptors in the lungs, which can reduce the bronchodilation effect of beta agonists or other asthma medications. This can worsen the asthma symptoms and cause wheezing, coughing, dyspnea, or chest tightness. The nurse should monitor the client for these signs and report them to the prescriber immediately.
