Nursing Elites

1. What is the most common cause of peptic ulcers?

• A. Helicobacter pylori infection
• B. NSAID use
• C. Excessive alcohol consumption
• D. Stress

Correct answer: A

Rationale: Helicobacter pylori infection is the most common cause of peptic ulcers. This bacterium can weaken the protective mucous coating of the stomach and duodenum, allowing acid to get through to the sensitive lining beneath. NSAID use (Choice B) can also cause peptic ulcers by disrupting the stomach's mucosal barrier. Excessive alcohol consumption (Choice C) and stress (Choice D) can exacerbate and contribute to ulcer formation but are not the primary cause.

2. A client with cholelithiasis is admitted with jaundice due to obstruction of the common bile duct. Which finding is most important for the nurse to report to the healthcare provider?

• A. Distended, hard, and rigid abdomen
• B. Clay-colored stool
• C. Radiating sharp pain in the right shoulder
• D. Bile-stained emesis

Correct answer: A

Rationale: The most important finding for the nurse to report to the healthcare provider in a client with cholelithiasis and jaundice due to common bile duct obstruction is a distended, hard, and rigid abdomen. These signs may indicate a possible surgical emergency, such as a complication like gallbladder perforation or peritonitis, which require immediate intervention. Clay-colored stool is associated with obstructive jaundice but does not indicate an acute surgical emergency. Radiating sharp pain in the right shoulder (referred pain from the diaphragm) and bile-stained emesis may also be seen in cholelithiasis but are not as urgent as a distended, hard, and rigid abdomen.

3. A nurse teaches clients about the difference between urge incontinence and stress incontinence. Which statements should the nurse include in this education? (Select all that apply.)

• A. Urge incontinence involves a post-void residual volume less than 50 mL.
• B. Stress incontinence occurs due to weak pelvic floor muscles.
• C. Stress incontinence usually occurs in people with dementia.
• D. Urge incontinence can be managed by increasing fluid intake.

Correct answer: B

Rationale: The correct statement to include in the education about urge incontinence and stress incontinence is choice B. Stress incontinence occurs due to weak pelvic floor muscles or urethral sphincter, leading to the inability to tighten the urethra sufficiently to overcome increased detrusor pressure. This condition is common after childbirth when pelvic muscles are stretched and weakened. Urge incontinence, on the other hand, is characterized by the inability to suppress the contraction signal from the detrusor muscle. It is often associated with abnormal detrusor contractions, which can be due to neurological abnormalities rather than post-void residual volume. Choice A is incorrect because urge incontinence is not defined by post-void residual volume. Choice C is incorrect as stress incontinence is not usually linked to dementia. Choice D is incorrect because increasing fluid intake is not a management strategy for urge incontinence.

4. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?

• A. As a single-dose 200 mEq oral tablet
• B. As an intravenous bolus over 15 to 20 minutes
• C. In an intravenous solution at a rate of 10 mEq/hour
• D. In an intravenous solution at a rate of 45 mEq/hour

Correct answer: C

Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.

5. When assessing the lower extremities of a client with peripheral vascular disease (PVD), the nurse notes bilateral ankle edema. The edema is related to:

• A. Competent venous valves.
• B. Decreased blood volume.
• C. Increase in muscular activity.
• D. Increased venous pressure.

Correct answer: D

Rationale: The correct answer is 'Increased venous pressure.' In peripheral vascular disease (PVD), impaired blood flow leads to increased venous pressure in the lower extremities, causing fluid to leak out of the blood vessels and accumulate as edema. Choice A, 'Competent venous valves,' is incorrect because in PVD, the venous valves may be incompetent, contributing to venous pooling and edema. Choice B, 'Decreased blood volume,' is incorrect as PVD is associated with impaired blood flow rather than reduced blood volume. Choice C, 'Increase in muscular activity,' is incorrect as it does not directly relate to the development of edema in PVD.
