Nursing Elites

1. Which of the following procedures describes an opening between the colon and abdominal wall?

• A. ileostomy
• B. jejunostomy
• C. colostomy
• D. cecostomy

Correct answer: C

Rationale: A colostomy is an opening between the colon and abdominal wall. An ileostomy is an opening between the ileum and abdominal wall, not the colon. Jejunostomy is an opening between the jejunum and abdominal wall, and cecostomy is an opening into the cecum. The term 'colostomy' specifically refers to the surgical procedure where a part of the colon is brought through the abdominal wall to create a stoma, allowing feces to leave the body. Therefore, the correct answer is colostomy as it accurately describes the opening between the colon and the abdominal wall, distinct from the other options.

2. The client has jaundice, elevated liver enzymes, and an elevated serum bilirubin. What color urine does the nurse expect to find?

• A. Pink-tinged
• B. Straw-colored
• C. Clear
• D. Dark amber

Correct answer: D

Rationale: The correct answer is dark amber. In jaundice, the elevated bilirubin levels are excreted in the urine, giving it a dark amber color. Choices A, B, and C are incorrect because in jaundice, the urine typically appears dark amber due to the presence of elevated bilirubin, not pink-tinged, straw-colored, or clear.

3. A patient asks a nurse the following question: Exposure to TB can be best identified with which of the following procedures?

• A. Chest x-ray
• B. Mantoux test
• C. Breath sounds examination
• D. Sputum culture for Mycobacterium tuberculosis

Correct answer: B

Rationale: The Mantoux test, also known as the tuberculin skin test, is the most appropriate and accurate test to identify exposure to TB. This test involves injecting a small amount of PPD tuberculin under the top layer of the skin, and a positive reaction indicates exposure to the TB bacteria. Choice A, a chest x-ray, is useful for detecting active TB disease but not exposure. Choice C, a breath sounds examination, is not a specific test for TB exposure. Choice D, a sputum culture for Mycobacterium tuberculosis, is used to diagnose active TB infection rather than exposure.

4. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:

• A. a maintenance dose.
• B. a loading dose.
• C. a medication with no first-pass effect.
• D. the medication to be given intravenously.

Correct answer: B

Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.

5. The nurse is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?

• A. Potassium.
• B. B-type natriuretic peptide (BNP).
• C. C-reactive protein (CRP).
• D. Platelets.

Correct answer: B

Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.
