Nursing Elites

1. Which of the following organs of the digestive system has a primary function of absorption?

• A. stomach
• B. pancreas
• C. small intestine
• D. gallbladder

Correct answer: C

Rationale: The small intestine is the correct answer. It is the primary organ responsible for absorption in the digestive system. The stomach's primary function is to break down food through mechanical and chemical digestion. The pancreas produces digestive enzymes to aid in the breakdown of food. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. However, neither the stomach, pancreas, nor gallbladder play the primary role of absorption in the digestive process, making them incorrect choices.

2. A physician orders a serum creatinine for a hospitalized client. The nurse should explain to the client and his family that this test:

• A. is normal if the level is 4.0 to 5.5 mg/dl.
• B. can be elevated with increased protein intake.
• C. is a better indicator of renal function than the BUN.
• D. reflects the fluid volume status of a person

Correct answer: C

Rationale: A serum creatinine level should be 0.7 to 1.5 mg/dl, and it does not vary with increased protein intake, so it is a better indicator of renal function than the BUN. Choice A is incorrect as a serum creatinine level of 4.0 to 5.5 mg/dl is not normal. Choice B is incorrect as serum creatinine is not affected by increased protein intake. Choice D is incorrect as serum creatinine primarily reflects renal function, not fluid volume status.

3. Which microorganism is most commonly associated with gastritis?

• A. Syphilis
• B. Cytomegalovirus
• C. H. pylori
• D. Mycobacterium

Correct answer: C

Rationale: H. pylori is the most common microorganism associated with gastritis, present in over 80% of cases. While syphilis, cytomegalovirus, and mycobacterium can also cause gastritis, they are much less prevalent compared to H. pylori. Therefore, the correct answer is H. pylori.

4. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?

• A. Use a soft toothbrush.
• B. Use dental floss daily.
• C. Hold pressure on any scrapes for 1-2 minutes.
• D. Use a triple-edged razor.

Correct answer: A

Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.

5. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?

• A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
• B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
• C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
• D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.

Correct answer: A

Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.
