A nurse is assessing a client who has muscarinic agonist poisoning. Following administration of atropine, which of the following findings should indicate to the nurse that the treatment has been effective?

Hyperactive bowel sounds

Heart rate 90/min

Blood pressure 90/50 mm Hg

Increased salivation

Answer and Explanation

The Correct Answer is B

A.   Hyperactive bowel sounds: Muscarinic agonist poisoning typically results in increased gastrointestinal motility and hyperactive bowel sounds. Atropine, an anticholinergic medication, works by blocking muscarinic receptors and reducing gastrointestinal motility. Therefore, the presence of hyperactive bowel sounds may indicate ongoing muscarinic stimulation and inadequate treatment with atropine.
B.   Heart rate 90/min: Atropine is an anticholinergic medication that increases heart rate by blocking the parasympathetic effects of acetylcholine on the heart. Bradycardia is a common manifestation of muscarinic agonist poisoning, and an increase in heart rate following atropine administration indicates reversal of this effect and effective treatment.
C.   Blood pressure 90/50 mm Hg: Atropine administration may result in transient hypertension due to its effect on increasing heart rate and cardiac output. Hypotension is a common
manifestation of muscarinic agonist poisoning, and an increase in blood pressure following atropine administration may indicate improvement in cardiovascular function. Therefore, a blood pressure of 90/50 mm Hg may not necessarily indicate effective treatment with atropine.
D.   Increased salivation: Muscarinic agonist poisoning typically results in excessive salivation (sialorrhea) due to stimulation of muscarinic receptors in the salivary glands. Atropine administration works by blocking these muscarinic receptors and reducing salivation. Therefore, increased salivation would indicate ongoing muscarinic stimulation and inadequate treatment with atropine.

Correct Answer is ["500"]

Explanation

To calculate the dose of erythromycin per administration, you can follow these steps:

- Determine the total daily dose: 2 g.

- Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =

0.5 g per dose.

- Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.

So, the nurse should administer 500 mg of erythromycin per dose.

A. Endocarditis B. Kidney transplant C. Seizures D. Hypokalemia

Correct Answer is A

Explanation

A. Endocarditis: Metronidazole is an antibiotic commonly used to treat infections caused by anaerobic bacteria, including certain types of endocarditis.
B. Kidney transplant: Metronidazole is not typically indicated for kidney transplant. Other antibiotics may be used in post-transplant care to prevent or treat infections.
C. Seizures: Metronidazole is not indicated for seizures. In fact, it may rarely cause neurological side effects such as seizures, but it is not typically used to treat seizures.
D. Hypokalemia: Metronidazole is not indicated for hypokalemia. It is an antibiotic and does not directly affect potassium levels.
