Nursing Elites

1. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?

• A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
• B. Absent peristalsis and elevated LES pressure
• C. Absent peristalsis and decreased LES pressure
• D. Vigorous peristalsis and decreased LES pressure

Correct answer: C

Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.

2. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?

• A. 20 mcg
• B. 15 mcg
• C. 25 mcg
• D. 30 mcg

Correct answer: A

Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.

3. A client is scheduled for a colonoscopy. Which instruction should the nurse provide?

• A. Eat a light breakfast on the day of the procedure.
• B. You will need to drink a bowel preparation solution before the procedure.
• C. Avoid all liquids for 24 hours before the procedure.
• D. You can continue taking your blood thinners until the day of the procedure.

Correct answer: B

Rationale: The correct instruction for a client scheduled for a colonoscopy is to drink a bowel preparation solution before the procedure. This solution helps cleanse the colon, ensuring clear visualization during the colonoscopy procedure. Choice A is incorrect because a light breakfast is usually recommended the day before the procedure, not on the day of the colonoscopy. Choice C is incorrect as it is important to stay hydrated and follow specific instructions regarding liquid intake. Choice D is incorrect as blood thinners may need to be adjusted or stopped before the colonoscopy to reduce the risk of bleeding during the procedure.

4. The sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?

• A. In most cases, breast cancer is not caused by the BRCA gene.
• B. It depends on how you will feel if the test is positive for the BRCA gene.
• C. There are many things to consider before deciding to have genetic testing.
• D. You should decide first whether you are willing to have a bilateral mastectomy.

Correct answer: C

Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.

5. What is the primary action of digoxin when prescribed to a patient with heart failure?

• A. Increase heart rate
• B. Decrease cardiac output
• C. Strengthen cardiac contractions
• D. Lower blood pressure

Correct answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.
