Nursing Elites

1. A systolic blood pressure of 145 mm Hg is classified as:

• A. Normotensive
• B. Prehypertension
• C. Stage I hypertension
• D. Stage II hypertension

Correct answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

2. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?

• A. The absence of special cells in the rectum caused the disease.
• B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
• C. The disease does not occur due to increased bowel motility leading to spasm and pain.
• D. The disease is not caused by the inability to tolerate sugar found in dairy products.

Correct answer: A

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.

3. 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.

4. A patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?

• A. Ask the patient to lie down to complete a full physical assessment.
• B. Briefly ask specific questions about this episode of respiratory distress.
• C. Complete the admission database to check for allergies before treatment.
• D. Delay the physical assessment to first complete pulmonary function tests.

Correct answer: B

Rationale: When a patient presents with acute shortness of breath, the initial assessment should focus on gathering specific information relevant to the current episode of respiratory distress. A comprehensive health history or full physical examination can be deferred until the acute distress has been addressed. Asking specific questions helps determine the cause of the distress and guides appropriate treatment. While checking for allergies is important, completing the entire admission database is not a priority during the initial assessment. Likewise, delaying the physical assessment for pulmonary function tests is not recommended as the immediate focus should be on addressing the acute respiratory distress before ordering further diagnostic tests or interventions.

5. 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.
