Nursing Elites

1. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?

• A. Stroke volume
• B. Cardiac output
• C. Venous pressure
• D. Left ventricular functioning

Correct answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.

2. When administering a shot of Vitamin K to a 30-day-old infant, which of the following target areas is the most appropriate?

• A. Gluteus maximus
• B. Gluteus minimus
• C. Vastus lateralis
• D. Vastus medialis

Correct answer: C

Rationale: When administering medications to infants, it is common to use the vastus lateralis muscle in the thigh for injections. The preferred site is the junction of the upper and middle thirds of the vastus lateralis muscle. This area provides a good muscle mass for the injection and minimizes the risk of hitting nerves or blood vessels. The gluteus maximus and gluteus minimus are not typically used for infant injections due to the risk of injury to the sciatic nerve. The vastus medialis is not as commonly used as the vastus lateralis for infant injections.

3. A client is found unresponsive in his room by a nurse. The client is not breathing and does not have a pulse. After calling for help, what is the next action the nurse should take?

• A. Administer 2 ventilations
• B. Perform a head-tilt, chin lift to open the airway
• C. Begin chest compressions
• D. Perform a jaw thrust to open the airway

Correct answer: C

Rationale: After finding an unresponsive client who is not breathing and has no pulse, the nurse's immediate action should be to call for help and start chest compressions. Chest compressions should be initiated at a rate of at least 100 per minute and a depth of at least 2 inches. Choice A, administering ventilations, is not the initial step as compressions take priority. Choice B, performing a head-tilt, chin lift, is also not the first step; chest compressions are crucial before airway management. Choice D, performing a jaw thrust, is typically used in cases of suspected cervical spine injury and is not the immediate action in this scenario.

4. A healthcare professional is putting together a presentation on meningitis. Which of the following microorganisms has not been linked to meningitis in humans?

• A. S. pneumoniae
• B. H. influenzae
• C. N. meningitidis
• D. Cl. difficile

Correct answer: D

Rationale: The correct answer is Cl. difficile. Clostridium difficile (C. diff) is not typically associated with meningitis in humans. This bacterium is known to cause severe diarrhea, usually as a result of antibiotic treatment. S. pneumoniae, H. influenzae, and N. meningitidis are all known to be causative agents of meningitis in humans. S. pneumoniae is a common cause of bacterial meningitis, especially in adults. H. influenzae, particularly type b (Hib), used to be a leading cause of meningitis in children before the introduction of the Hib vaccine. N. meningitidis is another significant pathogen responsible for causing meningitis, especially in young adults and adolescents.

5. Signs and symptoms of stroke may include all of the following EXCEPT:

• A. Sudden weakness or numbness of the face, arm, or leg.
• B. Sudden confusion.
• C. Sudden headache with no known cause.
• D. Hypotension.

Correct answer: D

Rationale: Hypotension is not a typical sign or symptom of an acute stroke. The correct signs and symptoms of a stroke include sudden weakness or numbness of the face, arm, or leg, sudden confusion, and a sudden headache with no known cause. Hypotension, which refers to low blood pressure, is not a common indicator of a stroke. It is important to differentiate between hypotension and hypertension in the context of stroke symptoms, as hypertension (high blood pressure) is actually a risk factor for strokes. Sudden weakness, numbness, confusion, and headache are signs associated with a stroke due to a disruption in blood flow to the brain. Hypotension, on the other hand, primarily indicates low blood pressure and is not directly linked to the typical presentation of a stroke.
