Nursing Elites

1. A client asks the nurse if all donor blood products are cross-matched with the recipient to prevent a transfusion reaction. Which of the following always requires cross-matching?

• A. packed red blood cells
• B. platelets
• C. plasma
• D. granulocytes

Correct answer: A

Rationale: Corrected Rationale: Packed red blood cells contain antigens and antibodies that must be matched between the donor and recipient to prevent transfusion reactions. Platelets, plasma, and granulocytes do not contain red blood cells, so they do not require cross-matching. Platelets are matched based on ABO compatibility, while plasma and granulocytes are not routinely cross-matched as they lack red cell antigens.

2. In the United States, several definitions of death are currently being used. The definition that uses apnea testing and pupillary responses to light is termed:

• A. whole brain death.
• B. heart-lung death.
• C. circulatory death.
• D. higher brain death.

Correct answer: A

Rationale: The correct answer is 'whole brain death.' Most protocols for determining whole brain death require two separate clinical examinations, including the induction of painful stimuli, pupillary responses to light, oculovestibular testing, and apnea testing. This comprehensive approach ensures that all functions of the brain, including the brainstem, are evaluated to confirm the absence of brain function. Choices B and D are incorrect as they do not reflect the specific tests required for determining whole brain death. Choice C, 'circulatory death,' does not involve the evaluation of brain function and is not a current definition of death in the United States.

3. Tricyclics (Antidepressants) can sometimes have which of the following adverse effects on patients diagnosed with depression?

• A. Shortness of breath
• B. Fainting
• C. Large intestine ulcers
• D. Distal muscular weakness

Correct answer: B

Rationale: The correct answer is 'Fainting.' Tricyclic antidepressants can cause fainting and hypotension as adverse effects. Shortness of breath (Choice A) is not a common side effect of tricyclics. Large intestine ulcers (Choice C) are not typically associated with tricyclic antidepressants. Distal muscular weakness (Choice D) is not a common adverse effect of tricyclics but is commonly associated with other medications.

4. A client is given an opiate drug for pain relief following general anesthesia. The client becomes extremely somnolent with respiratory depression. The physician is likely to order the administration of:

• A. naloxone (Narcan)
• B. labetalol (Normodyne)
• C. neostigmine (Prostigmin)
• D. thiothixene (Navane)

Correct answer: A

Rationale: The correct answer is naloxone (Narcan). Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression and somnolence. In this scenario, the client's extreme somnolence and respiratory depression suggest an opioid overdose, making naloxone the appropriate choice to counteract these effects. Labetalol (Normodyne) is a nonselective beta-blocker used to treat hypertension, not opioid overdose. Neostigmine (Prostigmin) is a cholinesterase inhibitor used to reverse neuromuscular blockade, not opioid-induced respiratory depression. Thiothixene (Navane) is an antipsychotic medication used to treat schizophrenia and is not indicated for opioid overdose.

5. While the client is receiving quinidine, the nurse should monitor the ECG for:

• A. Peaked P wave
• B. Elevated ST segment
• C. Inverted T wave
• D. Prolonged QT interval

Correct answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.
