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. The nurse recognizes that teaching a 44-year-old woman following a laparoscopic cholecystectomy has been effective when the patient states which of the following?

• A. I can expect yellow-green drainage from the incision for a few days.
• B. I can remove the bandages on my incisions tomorrow and take a shower.
• C. I should plan to limit my activities and not return to work for 4 to 6 weeks.
• D. I will always need to maintain a low-fat diet since I no longer have a gallbladder.

Correct answer: B

Rationale: The correct answer is, 'I can remove the bandages on my incisions tomorrow and take a shower.' After a laparoscopic cholecystectomy, patients have Band-Aids over the incisions and can typically remove the bandages the next day. Patients are usually discharged the same or next day and have minimal restrictions on their daily activities. Yellow-green drainage from the incision would be abnormal, requiring the patient to contact their healthcare provider. While a low-fat diet may be recommended initially after surgery, it is not a lifelong requirement, as the body can adjust to the absence of the gallbladder over time. Choice A is incorrect as abnormal drainage should be reported. Choice C is incorrect as most patients can resume normal activities within a few days to a week. Choice D is incorrect as maintaining a low-fat diet is not a lifelong necessity after a cholecystectomy.

3. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

4. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

• A. The patient states he had a manic episode a week ago
• B. The patient states he has been having diarrhea every day
• C. The patient presents as severely depressed
• D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.

5. An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?

• A. Double the birth weight
• B. Triple the birth weight
• C. Gain 6 ounces each week
• D. Add 2 pounds each month

Correct answer: A

Rationale: Infants typically double their birth weight by 6 months of age as part of normal growth and development. This doubling of weight is a common milestone used by healthcare providers to assess a baby's growth progress. Tripling the birth weight or adding 2 pounds each month would result in excessive weight gain, which is not typical or healthy for an infant. Similarly, gaining 6 ounces each week would also lead to rapid and abnormal weight gain, making it an incorrect choice.
