Question 1 of 5
The nurse is caring for a patient who has a diagnosis of AIDS. Inspection of the patient's mouth reveals the new presence of white lesions on the patient's oral mucosa. What is the nurse's most appropriate response?
Correct Answer: D
Rationale: The nurse should inform the primary care provider of this abnormal finding in the patient's oral cavity, since it necessitates medical treatment. It would be inappropriate to try to remove skin lesions from a patient's mouth and salt water will not resolve this problem, which is likely due to candidiasis. A dietitian referral is unnecessary.
Question 2 of 5
A patient has been scheduled for a urea breath test in one month's time. What nursing diagnosis most likely prompted this diagnostic test?
Correct Answer: B
Rationale: Urea breath tests detect the presence of Helicobacter pylori, the bacteria that can live in the mucosal lining of the stomach and cause peptic ulcer disease. This test does not address fluid volume, nutritional status, or dentition.
Question 3 of 5
A female patient has presented to the emergency department with right upper quadrant pain; the physician has ordered abdominal ultrasound to rule out cholecystitis (gallbladder infection). The patient expresses concern to the nurse about the safety of this diagnostic procedure. How should the nurse best respond?
Correct Answer: B
Rationale: An ultrasound produces no ill effects and there are not specific limits on its use, even during pregnancy.
Question 4 of 5
A nurse is caring for a patient who is scheduled for a colonoscopy and whose bowel preparation will include polyethylene glycol electrolyte lavage prior to the procedure. The presence of what health problem would contraindicate the use of this form of bowel preparation?
Correct Answer: A
Rationale: The use of a lavage solution is contraindicated in patients with intestinal obstruction or inflammatory bowel disease. It can safely be used with patients who have polyps, colon cancer, or diverticulitis.
Question 5 of 5
A nurse is promoting increased protein intake to enhance a patient's wound healing. The nurse knows that enzymes are essential in the digestion of nutrients such as protein. What is the enzyme that initiates the digestion of protein?
Correct Answer: A
Rationale: The enzyme that initiates the digestion of protein is pepsin. Intrinsic factor combines with vitamin B12 for absorption by the ileum. Lipase aids in the digestion of fats and amylase aids in the digestion of starch.
