The nurse administers teriparatide and evaluates the drug as effective in achieving desired effects when what is assessed?

Decrease in serum calcium and increase in serum phosphorous.

Increase in serum calcium and decrease in serum phosphorous.

Increase in serum calcium and phosphorous.

Decrease in serum calcium and phosphorous.

Answer and Explanation

The Correct Answer is B

This is because teriparatide affects calcium and phosphorus metabolism in a pattern consistent with the known actions of endogenous PTH (eg, increases serum calcium and decreases serum phosphorus)12.

Choice A is wrong because teriparatide does not decrease serum calcium, but increases it.

Choice C is wrong because teriparatide does not increase serum phosphorus, but decreases it.

Choice D is wrong because teriparatide does not decrease serum calcium, but increases it.

Normal ranges for serum calcium are 8.5 to 10.2 mg/dL and for serum phosphorus are 2.5 to 4.5 mg/dL.

Correct Answer is A

Explanation

This is because phenothiazines are contraindicated in patients with suspected or established subcortical brain damage. Phenothiazines can cause central nervous system effects such as drowsiness, dizziness, and extrapyramidal symptoms that may worsen the condition of a client with a brain injury.

Choice B is wrong because phenothiazines are not contraindicated in clients with ischemic heart disease.

However, they should be used with caution as they can cause hypotension and cardiac arrhythmias.

Choice C is wrong because phenothiazines are not contraindicated in pediatric clients.

However, they should be used with caution as they can cause sedation, anticholinergic effects, and paradoxical excitement.

Choice D is wrong because phenothiazines are not contraindicated in clients with type 2 diabetes.

However, they should be used with caution as they can cause hyperglycemia and alter the effects of antidiabetic drugs.

A. 800 mg PO at bedtime. B. 150 mg PO b.i.d. C. 20 mg PO b.i.d. D. 300 mg PO at bedtime.

Correct Answer is A

Explanation

800 mg PO at bedtime is an appropriate dosage and frequency of cimetidine for the treatment of gastric ulcer. Cimetidine is a histamine H antagonist that reduces the secretion of gastric acid.

Choice B is wrong because 150 mg PO b.i.d. is too low of a dose for cimetidine. The usual adult dose for duodenal ulcer is 800 mg PO once a day at bedtime or 300 mg PO four times a day.

Choice C is wrong because 20 mg PO b.i.d. is not a valid dose for cimetidine.

The lowest available tablet strength is 100 mg.

Choice D is wrong because 300 mg PO at bedtime is also too low of a dose for cimetidine.

The usual adult dose for gastric ulcer is 800 mg PO once a day at bedtime or 300 mg PO four times a day.
