The nurse administers IV potassium chloride to a client with hypokalemia. Which precaution should the nurse take?

Correct Answer: C

Rationale: Potassium chloride corrects hypokalemia but is caustic IV, risking phlebitis or tissue damage if it infiltrates. Monitoring the IV site prevents complications, a key precaution. Undiluted or rapid infusion causes burns or arrhythmias'standard is diluted, <10 mEq/hour. A syringe pump isn't required'IV pumps suffice. Site monitoring aligns with potassium's administration risks, critical in hypokalemia where cardiac effects (e.g., arrhythmias) are at stake, making C the nurse's priority to ensure safe delivery.

Correct Answer: A

Rationale: Albuterol's inhalation targets lungs directly, with rapid absorption for quick relief (minutes vs. hours for oral). Pills work but slower. Side effects differ, not the reason. Efficacy varies by route. A explains pharmacokinetics, making it the best response.

Correct Answer: B

Rationale: Morphine, an opioid, improves chronic diarrhea by increasing intestinal circular muscle tone . Opioids slow GI motility via μ-receptors, enhancing tone and reducing peristalsis. Option , improved motility, opposes this. Options , , and (E) weaken continence or motility, not fitting. This constipating effect explains the improvement, a common opioid side effect.

Correct Answer: A

Rationale: Meperidine hydrochloride (Demerol) is an opioid analgesic used for pain relief, but it is known to cause side effects. Tremors are not a common side effect associated with Meperidine. Diarrhea, sweating, and dizziness are commonly reported side effects of this medication. Tremors are more commonly associated with stimulant medications or conditions like anxiety or certain neurological disorders.

Correct Answer: A

Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin therapy. Green tea is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Maintaining a consistent intake of vitamin K is important for patients on warfarin in order to keep their INR (International Normalized Ratio) levels stable. It is not necessary to avoid all sources of vitamin K, but rather to keep intake consistent and moderate. Drinking large amounts of green tea, which is high in vitamin K, can potentially impact the patient's INR levels and increase the risk of bleeding or clotting issues.
