Furosemide (Lasix) is prescribed for a patient who is about to be discharged, and the nurse provides instructions to the patient about the medication. Which statement by the nurse is correct?

Correct Answer: D

Rationale: The correct statement by the nurse is D. "Be sure to change positions slowly and rise slowly after sitting or lying so as to prevent dizziness and possible fainting because of blood pressure changes." This instruction is important for patients taking furosemide (Lasix) because this medication can cause changes in blood pressure, especially when changing positions quickly. By rising slowly, the patient can minimize the risk of dizziness or fainting. This precaution is crucial to ensure patient safety while taking furosemide.

Correct Answer: C

Rationale: Redness and pain at the site of the infusion are important signs of a potential infiltration or extravasation of the medication, in this case pentamidine (Pentam) IV. Pentamidine is an antimicrobial medication used to treat and prevent Pneumocystis jiroveci pneumonia (PCP) in patients who are immunocompromised, such as those with HIV. Infiltration or extravasation of IV medications can lead to significant tissue damage, necrosis, and other complications. Therefore, it is crucial to immediately address any signs of redness and pain at the infusion site to prevent further harm to the patient. This assessment finding should be promptly relayed to the physician for appropriate management, which may include discontinuation of the infusion, monitoring for complications, and providing alternative treatments if necessary. The other assessment findings (blood pressure of 100/62 mm/Hg

Correct Answer: B

Rationale: Lithium is primarily used in the treatment of bipolar disorder to decrease the incidence of acute manic episodes. It helps to stabilize mood and prevent the extreme highs (manic episodes) associated with bipolar disorder. Lithium is not used to decrease blood pressure, seizure activity, or increase urinary output.

Correct Answer: B

Rationale: Naloxone is the appropriate medication to be administered to a patient with a suspected opioid overdose. Naloxone is an opioid receptor antagonist, meaning it can quickly reverse the effects of opioids on the central nervous system. It works by binding to the same receptors in the brain that opioids target, blocking their effects and rapidly restoring normal respiration and consciousness in a person who has overdosed on opioids. This can be a life-saving treatment for opioid overdose patients. Exenatide, Heparin, and Tolvaptan are not appropriate medications for reversing opioid overdose.

Correct Answer: C

Rationale: The therapeutic range for Lithium is typically considered to be 0.6-1.2 mEq/L for maintenance treatment. However, some sources may also suggest a wider therapeutic range of 0.5-2 mEq/L. Monitoring serum lithium levels is crucial to ensure that the patient is within the therapeutic range and to adjust the dosage accordingly to avoid toxicity or subtherapeutic levels. Thus, option C (0.5-2) provides a more comprehensive and inclusive range that is commonly referenced in clinical practice.
