For which client would the use of a phenothiazine most likely be contraindicated?

A client being treated for a traumatic brain injury.

A client with a history of ischemic heart disease.

A pediatric client.

A client with type 2 diabetes.

Answer and Explanation

The Correct Answer is A

Phenothiazines are contraindicated in patients with suspected or established subcortical brain damage. Phenothiazines are a class of drugs that have antipsychotic, antiemetic, and sedative effects. They act by blocking dopamine receptors in the brain and can cause extrapyramidal symptoms, hypotension, and anticholinergic effects.

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

However, they can cause orthostatic hypotension and cardiac arrhythmias, so they should be used with caution and monitored closely in these patients.

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

However, they can cause sedation, hypotension, and extrapyramidal symptoms, so they should be used with caution and at lower doses in these patients.

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

However, they can cause hyperglycemia and weight gain, so they should be used with caution and monitored closely in these patients.

Correct Answer is C

Explanation

This is because aprepitant can cause dehydration as an adverse effect, so the nurse will want to encourage the client to drink as much liquid as possible.

Choice A is wrong because the client’s temperature would not be affected by aprepitant.

Choice B is wrong because the client must be encouraged for fluid intake as tolerated, so placing an NPO sign on the door would not be appropriate for this client.

Choice D is wrong because elevating the head of the bed would be unnecessary for a client receiving aprepitant.

A. Decrease in serum calcium and increase in serum phosphorous. B. Increase in serum calcium and decrease in serum phosphorous. C. Increase in serum calcium and phosphorous. D. Decrease in serum calcium and phosphorous.

Correct Answer is B

Explanation

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.
