A nurse is planning care for a client who has a prescription for acetazolamide.
Which of the following findings should the nurse plan to monitor for as an adverse effect of this medication?

Bronchospasm.

Constipation.

Diplopia.

Electrolyte imbalance.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Bronchospasm is a constriction of the airways, commonly seen in respiratory conditions like asthma. It is mediated by inflammatory responses and smooth muscle contraction in the bronchi. Acetazolamide, a carbonic anhydrase inhibitor, does not typically cause bronchospasm; its primary effects are on fluid and electrolyte balance and intraocular pressure.

Choice B rationale

Constipation is a common gastrointestinal symptom characterized by infrequent or difficult bowel movements. It can be caused by various factors, including dietary habits, medications, and underlying medical conditions. Acetazolamide's mechanism of action, involving inhibition of carbonic anhydrase, does not directly lead to constipation as a significant adverse effect.

Choice C rationale

Diplopia, or double vision, is a visual disturbance where a single object appears as two. It can result from ocular muscle weakness, nerve damage, or other neurological conditions. Acetazolamide's therapeutic effects are on aqueous humor production in the eye to reduce intraocular pressure, but diplopia is not a recognized adverse effect of this medication.

Choice D rationale

Acetazolamide is a carbonic anhydrase inhibitor that promotes the excretion of bicarbonate, sodium, potassium, and water. This diuretic action can lead to metabolic acidosis, hypokalemia (normal range: 3.5-5.0 mEq/L), and hyponatremia (normal range: 135-145 mEq/L) due to increased renal excretion, hence requiring close monitoring of electrolyte balance.

Correct Answer is ["3"]

Explanation

Step 1 is: Convert client weight from pounds to kilograms. 165 Ib ÷ 2.2 Ib/kg = 75 kg.

Step 2 is: Calculate the total dose of verapamil needed. 0.1 mg/kg × 75 kg = 7.5 mg.

Step 3 is: Calculate the volume to administer in mL. 7.5 mg ÷ (2.5 mg/mL) = 3 mL. The nurse should administer 3 mL.

A. Disulfiram. B. Flumazenil. C. Naloxone. D. Dantrolene.

Correct Answer is B

Explanation

Choice A rationale

Disulfiram is an aldehyde dehydrogenase inhibitor used in the treatment of chronic alcoholism. It works by blocking the metabolism of ethanol, leading to the accumulation of acetaldehyde, which produces unpleasant physical reactions when alcohol is consumed. It has no pharmacological effect on benzodiazepine overdose.

Choice B rationale

Flumazenil is a competitive benzodiazepine receptor antagonist that rapidly reverses the sedative and other central nervous system effects of benzodiazepine overdose. It acts by binding to the gamma-aminobutyric acid (GABA) receptor complex, thereby displacing benzodiazepines and restoring normal neurological function.

Choice C rationale

Naloxone is an opioid receptor antagonist primarily used to reverse opioid overdose. It competitively binds to opioid receptors, particularly mu receptors, thereby blocking the effects of opioid agonists and reversing respiratory depression and other opioid-induced central nervous system depression. It does not affect benzodiazepines.

Choice D rationale

Dantrolene is a direct-acting skeletal muscle relaxant primarily used in the treatment of malignant hyperthermia and spasticity. It works by interfering with calcium release from the sarcoplasmic reticulum in muscle cells, reducing muscle contraction. It has no role in reversing benzodiazepine overdose.
