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.

Correct Answer is A
Explanation
The nurse should ask this question because the client is taking a chemical stimulant laxative, which can cause dehydration and electrolyte imbalance, especially in combination with medications for heart failure and osteoarthritis that may also affect fluid and electrolyte balance. The nurse should assess the client’s hydration status and risk of hypovolemia or hypotension.
Choice B. Timing of medication administration is wrong because it is not the priority question in this situation.
The nurse should ask this question later to determine if the client is taking the medications as prescribed and if there are any drug interactions or adverse effects.
Choice C. Previous effectiveness of laxatives is wrong because it is not relevant to the client’s current condition.
The nurse should ask this question later to evaluate the client’s bowel habits and history of constipation.
Choice D. The amount of fiber intake is wrong because it is not the priority question in this situation.
The nurse should ask this question later to educate the client about dietary measures to prevent constipation and promote bowel health.
Correct Answer is B
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.
It does not have a significant interaction with corticosteroids.
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.
It does not have a significant interaction with corticosteroids.
