Nursing Elites

1. A 24-year-old female contracts hepatitis from contaminated food. During the acute (icteric) phase of the patient's illness, what would serologic testing most likely reveal?

• A. antibody to hepatitis D (anti-HDV).
• B. hepatitis B surface antigen (HBsAg).
• C. anti-hepatitis A virus immunoglobulin G (anti-HAV IgG).
• D. anti-hepatitis A virus immunoglobulin M (anti-HAV IgM).

Correct answer: D

Rationale: Hepatitis A is primarily transmitted through the oral-fecal route. During the acute phase of hepatitis A, serologic testing typically reveals anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). This antibody appears early in the course of the infection. The presence of anti-HAV IgM indicates an acute infection with hepatitis A. Choices A and B are incorrect as hepatitis D and hepatitis B antigens are not typically associated with acute hepatitis A. Choice C, anti-hepatitis A virus immunoglobulin G (anti-HAV IgG), would indicate a past infection and lifelong immunity, which is not expected during the acute phase of the illness.

2. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

3. What preparation should be made for a client undergoing a KUB (Kidney, Ureter, Bladder) radiography test?

• A. Client must be NPO before the examination
• B. Enema should be administered before the examination
• C. Medicate the client with furosemide 20 mg IV 30 minutes before the examination
• D. No special orders are necessary for this examination

Correct answer: D

Rationale: The correct answer is that no special orders are necessary for a KUB radiography test. It is important to inform the client to remove any clothing, jewelry, or objects that may interfere with the test. Option A is incorrect because there is no need for the client to be NPO before this examination. Option B is incorrect as enemas are not routinely administered prior to a KUB radiography test. Option C is incorrect as there is no need to medicate the client with furosemide before this examination.

4. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

5. The nurse is preparing to care for a child with a diagnosis of intussusception. The nurse reviews the child's record and expects to note which sign of this disorder documented?

• A. Watery diarrhea
• B. Ribbon-like stools
• C. Profuse projectile vomiting
• D. Bright red blood and mucus in the stools

Correct answer: D

Rationale: Intussusception is a condition where a part of the bowel slides into the next section, causing an obstruction. The classic presentation includes severe abdominal pain that is crampy, intermittent, and may cause the child to draw knees to the chest. While vomiting can occur, it is not typically projectile in nature. A key hallmark of intussusception is the passage of bright red blood and mucus in the stools, often described as currant jelly-like. Watery diarrhea and ribbon-like stools are not typical signs of intussusception and should not be expected in a child with this condition.
