A nurse is caring for a client who has a prescription for long-acting insulin glargine. Which of the following actions should the nurse take?
Store the medication vial in a freezer until ready for use.
Let the medication warm to room temperature prior to administration.
Store opened vials at room temperature for up to 3 months.
Agitate the medication vial between the palms of the hands before use.
The Correct Answer is B
A. Store the medication vial in a freezer until ready for use: Insulin should never be frozen, as freezing alters its molecular structure and renders it ineffective. It should be refrigerated until opened.
B. Let the medication warm to room temperature prior to administration: Allowing insulin glargine to reach room temperature before injection reduces local discomfort and ensures consistent absorption. This is the recommended practice for all insulin types.
C. Store opened vials at room temperature for up to 3 months: Opened insulin vials may be kept at room temperature for up to 28 days, not 3 months. Extended storage at room temperature increases the risk of potency loss.
D. Agitate the medication vial between the palms of the hands before use: Insulin glargine is a clear solution and should not be agitated or mixed. Shaking can cause air bubbles or damage the insulin molecules, leading to inaccurate dosing.

Correct Answer is A
Explanation
A. "I should monitor the client's electrolytes.": Sodium polystyrene sulfonate (Kayexalate) exchanges sodium for potassium in the intestines, lowering serum potassium levels. Monitoring electrolytes is essential to evaluate therapeutic effectiveness and prevent imbalances such as hypokalemia or hypernatremia.
B. "Antacids can be taken with this medication.": Antacids containing calcium or magnesium can interfere with the medication’s ion-exchange mechanism and increase the risk of systemic absorption, leading to metabolic complications. They should be avoided.
C. "I should administer this medication intravenously.": Sodium polystyrene sulfonate is administered orally or rectally, not intravenously. IV administration would be unsafe and is contraindicated due to the drug’s formulation and mechanism.
D. "This medication is safe to take with sorbitol.": Concomitant use with sorbitol is avoided because it increases the risk of intestinal necrosis. These agents should not be used together due to their additive gastrointestinal effects.
Correct Answer is B
Explanation
A. Low-grade fever: A mild fever is not typically associated with the interaction between morphine and amitriptyline. It may indicate an unrelated infection or inflammatory process rather than a medication effect.
B. Urinary retention: Both morphine (an opioid) and amitriptyline (a tricyclic antidepressant) have anticholinergic properties that can decrease bladder tone and inhibit urination. When combined, they increase the risk of urinary retention, making this a significant adverse interaction.
C. Diarrhea: These medications more commonly cause constipation rather than diarrhea because of their combined effects on slowing gastrointestinal motility. Diarrhea would not indicate an interaction between the two drugs.
D. Tachypnea: Morphine typically causes respiratory depression rather than an increased respiratory rate. Tachypnea would not be a sign of interaction but could occur as a compensatory response to pain or anxiety.
