A nurse is caring for a client who is taking lithium and reports starting a new exercise program.
The nurse should assess the client for which of the following electrolyte imbalances?

Hypomagnesemia.

Hypocalcemia.

Hyponatremia.

Hypokalemia.

Answer and Explanation

The Correct Answer is C

Lithium can cause hyponatremia by increasing the secretion of antidiuretic hormone and reducing the renal clearance of sodium.

Strenuous exercise can also cause hyponatremia by increasing sweat loss and fluid intake. Therefore, a client who is taking lithium and starting a new exercise program is at risk of developing hyponatremia.

Choice A is wrong because hypomagnesemia is not a common side effect of lithium or exercise.

Choice B is wrong because hypocalcemia is not a common side effect of lithium or exercise.

Choice D is wrong because hypokalemia is not a common side effect of lithium or exercise.

However, lithium can interact with some diuretics that can cause hypokalemia, so the client should avoid taking these drugs without consulting their doctor. Normal ranges for electrolytes are:

Sodium: 135-145 mmol/L

Magnesium: 0.7-1.1 mmol/L

Calcium: 2.1-2.6 mmol/L

Potassium: 3.5-5.0 mmol/L

Correct Answer is C

Explanation

A therapeutic effect of naloxone is the reversal of opioid-induced respiratory depression, which is one of the most dangerous complications of opioid overdose. Naloxone works by binding to opioid receptors, displacing opioids, and restoring normal respiratory drive. An increase in respiratory rate after administration indicates that naloxone is effective.

Choice A is wrong because decreased blood pressure is not a therapeutic effect of naloxone.

In fact, naloxone can cause hypertension (high blood pressure) as a side effect due to opioid withdrawal.

Choice B is wrong because decreased nausea is not a therapeutic effect of naloxone. Nausea is a common side effect of morphine, but naloxone does not affect it directly.

Naloxone can actually cause nausea and vomiting as a side effect due to opioid withdrawal.

Choice D is wrong because increased pain relief is not a therapeutic effect of naloxone.

Pain relief is a desired effect of morphine, but naloxone antagonizes it by blocking the opioid receptors.

Naloxone can cause pain and discomfort as a side effect due to opioid withdrawal.

A. The client has a BUN level of 18 mg/dL. B. The client reports a history of nausea with cefuroxime. C. The client has a history of a severe penicillin allergy. D. The client takes an aspirin daily.

Correct Answer is C

Explanation

This is the priority for the nurse to report to the provider because cefuroxime is a cephalosporin antibiotic that can cause serious or life-threatening allergic reactions in people who are allergic to penicillin. The nurse should not administer cefuroxime to this client until the provider is notified and an alternative antibiotic is prescribed.

Choice A is wrong because the client has a BUN level of 18 mg/dL, which is within the normal range of 7 to 20 mg/dL.

This does not indicate any renal impairment or adverse reaction to cefuroxime.

Choice B is wrong because the client reports a history of nausea with cefuroxime, which is a common side effect of this drug.

The nurse should instruct the client to take cefuroxime with food to reduce nausea, but this is not a priority to report to the provider.

Choice D is wrong because the client takes aspirin daily, which does not interact with cefuroxime.

The nurse should monitor the client for any signs of bleeding or bruising while taking aspirin, but this is not a priority to report to the provider.
