The nurse is preparing to transfuse a patient with a unit of packed red blood cells (PRBCs). Which intravenous solution is correct for use with the PRBC transfusion?

Correct Answer: B

Rationale: 0.9% sodium chloride (NS), also known as normal saline, is the correct intravenous solution to use with packed red blood cell (PRBC) transfusion. NS is isotonic and compatible with blood products, making it the preferred solution for blood transfusions to prevent hemolysis of red blood cells. Other solutions such as D5W, D5NS, and D5LR are not recommended for use with PRBC transfusions due to their potential to cause hemolysis or affect the stability of the blood product.

Correct Answer: D

Rationale: Pain relief in pregnancy avoids fetal harm. Ketorolac , an NSAID, risks ductal closure, disrupting fetal circulation. Acetaminophen , Codeine , Hydrocodone , and Morphine (E) are safer. Ketorolac's prostaglandin inhibition contraindicates it late in gestation.

Correct Answer: B

Rationale: Lithium toxicity (e.g., tremors, confusion) at narrow therapeutic range (0.6-1.2) is life-threatening-knowing signs (e.g., nausea) and prevention (e.g., hydration) is priority, per safety. Work, ADLs, and mood stability follow but aren't immediate risks. Toxicity awareness saves lives, per education.

Correct Answer: D

Rationale: Acute interstitial nephritis is a rare but serious adverse reaction associated with omeprazole. It is characterized by inflammation of the kidney's interstitial tissue and can lead to kidney dysfunction. Symptoms may include fever, rash, eosinophilia, and impaired renal function. If left untreated, acute interstitial nephritis can progress to acute kidney injury and potentially be life-threatening. Therefore, it is essential to promptly recognize and manage this adverse reaction when taking omeprazole.

Correct Answer: D

Rationale: Conventional antipsychotics (e.g., haloperidol) cause anticholinergic effects like urinary retention , a potential emergency risking bladder damage, requiring immediate reporting. Dystonia is extrapyramidal, not anticholinergic. Headache and hypertension aren't typical anticholinergic signs. D prioritizes urgent intervention, making it the correct choice.
