Question 1 of 5
A client with bipolar disorder admitted with severe depression and suicidal ideation receives a prescription for lithium carbonate. Which instruction should the nurse provide to the client?
Correct Answer: A
Rationale: NSAIDs increase lithium levels, risking toxicity (e.g., tremors, confusion). Eliminating NSAIDs is critical. Glucose, dental notifications, and iodine foods are unrelated to lithium safety.
Question 2 of 5
A client with a cold is taking the antitussive medication benzonatate. Which assessment information indicates to the nurse that the medication is effective?
Correct Answer: D
Rationale: Benzonatate suppresses cough by numbing respiratory passages. No coughing spells indicates effectiveness. Expectorating, nasal discharge, or sleep are not direct measures of antitussive action.
Question 3 of 5
The nurse is administering sevelamer during lunch to a client with chronic kidney disease (CKD). The client asks the nurse to bring the medication later. The nurse should describe which action of sevelamer as an explanation for taking it with meals?
Correct Answer: D
Rationale: Sevelamer binds dietary phosphorus in the gut, reducing absorption in CKD to prevent hyperphosphatemia. Taking with meals ensures binding. Reflux, acid buffering, and indigestion are unrelated.
Question 4 of 5
The healthcare provider prescribes enoxaparin sodium 80 mg subcutaneously twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'enoxaparin sodium injection, USP 60 mg/0.6 mL'. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale: Calculate: (80 mg ÷ 60 mg) × 0.6 mL = 0.8 mL. The nurse should administer 0.8 mL to deliver 80 mg of enoxaparin.

Question 5 of 5
What actions should the nurse take to ensure safety during morphine administration? Select all that apply.
Correct Answer: A,D,E
Rationale: Morphine risks respiratory depression; checking respiratory rate, having a resuscitation bag, and reviewing medications for interactions ensure safety. ECG, suctioning, and restraints are unnecessary without specific indications.
