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.
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.

Explanation
The client should avoid taking aspirin while taking corticosteroids because of the potential drug-drug interaction between them. This interaction may cause a reduction in the blood levels of aspirin and decrease its effectiveness. It may also increase the risk of gastrointestinal side effects such as inflammation, bleeding, ulceration, and perforation.
Choice A is wrong because dimenhydrinate is an antihistamine that is used to prevent and treat nausea, vomiting, and dizziness.

Choice C is wrong because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, inflammation, and fever.
It has a similar interaction with corticosteroids as aspirin, but it is less potent and less likely to cause bleeding.
Choice D is wrong because famotidine is a histamine-2 receptor antagonist that is used to treat and prevent ulcers, gastroesophageal reflux disease (GERD), and other conditions that cause excess stomach acid.
