1. Which of the following is a fat-soluble vitamin?
- A. Vitamin C
- B. Vitamin D
- C. Vitamin B-6
- D. Riboflavin
Correct answer: B
Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
2. The nurse is preparing to assess a hospitalized patient who is experiencing significant shortness of breath. How should the nurse proceed with the assessment?
- A. Have the patient lie down to obtain an accurate cardiac, respiratory, and abdominal assessment.
- B. Obtain a thorough history and physical assessment from the patient's family member.
- C. Immediately perform a complete history and physical assessment to obtain baseline information.
- D. Examine the body areas relevant to the problem and complete the rest of the assessment after the problem has resolved.
Correct answer: D
Rationale: When assessing a patient experiencing significant shortness of breath, it is crucial to prioritize the evaluation of areas directly related to the problem. Having the patient lie down may exacerbate the breathing difficulty. Therefore, the nurse should focus on examining the body areas pertinent to the issue, such as the respiratory and cardiac systems. Completing the rest of the assessment can be deferred until after addressing the immediate problem. Obtaining a complete history or involving family members should come after addressing the acute issue to ensure the patient's safety and comfort.
3. What is the anatomic structure located in the middle of the heart that separates the right and left ventricles?
- A. Septum
- B. Sputum
- C. Separator
- D. None of the above
Correct answer: A
Rationale: The correct answer is the septum. The septum is a structure located in the middle of the heart that separates the right and left ventricles. It plays a crucial role in maintaining the separation between the two ventricles to ensure efficient blood flow. The other choices, 'Sputum' and 'Separator,' are incorrect as they do not refer to the anatomic structure in the heart that serves this specific function. 'Sputum' is a term used to describe phlegm or mucus, not an anatomical structure, and 'Separator' is a generic term that does not specifically identify the cardiac structure mentioned in the question.
4. When are manual hematocrits done?
- A. to monitor anemia
- B. by using a microhematocrit tube.
- C. to measure the percentage of plasma to cells.
- D. All of the above.
Correct answer: D
Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
5. What is the proper personal protective equipment necessary for collecting a sputum specimen?
- A. Gloves and face mask
- B. Level Three Biocontainment uniforms
- C. Eye protection and shoe covers
- D. Splash shield and face mask
Correct answer: A
Rationale: When collecting a sputum specimen, it is crucial to protect against potential airborne droplets that may spread disease. The best personal protective equipment for this task includes gloves and a face mask. Gloves help prevent the spread of contaminants through hand contact, while a face mask protects the respiratory tract from inhaling infectious agents. Choice B, Level Three Biocontainment uniforms, is excessive and unnecessary for routine sputum specimen collection. Choice C, eye protection and shoe covers, does not address the specific risks associated with sputum collection. Choice D, splash shield and face mask, provides additional protection that is not typically required for sputum specimen collection, making it less appropriate than gloves and a face mask.
