1. Which contraindication should be assessed for prior to administering an immunization to a child?
- A. Mild cold symptoms
- B. Chronic asthma
- C. Depressed immune system
- D. Allergy to eggs
Correct answer: C
Rationale: Before administering immunizations to children, it is crucial to assess for contraindications. A depressed immune system, such as that seen in conditions like HIV or due to chemotherapy, is a significant contraindication. Immunizations may not be safe or effective in children with compromised immune systems. Mild cold symptoms, although not ideal, are not a contraindication for routine immunizations. Chronic asthma, while a consideration, is not a direct contraindication for routine immunizations. Allergy to eggs is a contraindication for specific vaccines, such as influenza vaccine that is grown in eggs, but it is not a contraindication for all immunizations.
2. Which of the following statements best describes substance P?
- A. Substance P decreases a client's sensitivity to pain
- B. Substance P levels are drawn before administration of narcotic analgesics
- C. Substance P is found in the brain and is responsible for pain control and management of depression
- D. Substance P is found in the dorsal horn of the spinal column
Correct answer: D
Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
3. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?
- A. Pituitary
- B. Pineal
- C. Pancreas
- D. Hypothalamus
Correct answer: B
Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.
4. A nurse is preparing to insert a small-bore nasogastric feeding tube for a client's enteral feedings. In which method does the nurse measure the correct length of the tube?
- A. From the tip of the nose to the xiphoid process
- B. From the tip of the nose to the earlobe to the xiphoid process
- C. From the earlobe to the xiphoid process
- D. From the tip of the nose to the earlobe to the umbilicus
Correct answer: B
Rationale: When preparing to insert a nasogastric tube, the nurse must measure the correct length to ensure that the end of the tube will be in the correct position in the stomach. The accurate method to measure the length is from the tip of the nose to the earlobe to the xiphoid process. This length ensures that the end of the tube reaches the stomach, avoiding placement in the small intestine or esophagus. Choice A is incorrect as it does not include the earlobe, which is essential for accurate measurement. Choice C is incorrect because measuring from the earlobe alone does not provide the correct length for positioning in the stomach. Choice D is incorrect as it includes the umbilicus, which is not the appropriate landmark for measuring the length of a nasogastric tube intended for stomach placement.
5. While performing the physical examination, why does the nurse share information and briefly teach the patient?
- A. To help the patient feel more comfortable and gain control of the situation
- B. To build rapport and increase the patient's confidence in the examiner
- C. To assist the patient in understanding his or her disease process and treatment modalities
- D. To aid the patient in identifying questions about his or her disease and potential areas of needed education
Correct answer: B
Rationale: Sharing information and briefly teaching the patient during a physical examination helps build rapport and increase the patient's confidence in the examiner. This approach gives the patient a sense of control in a situation that can often be overwhelming. While sharing information may make the patient feel more comfortable, the primary goal is to enhance the patient's confidence in the examiner. Providing information does not necessarily directly assist the patient in understanding their disease process and treatment modalities, as this may require a more in-depth explanation. The main focus is on establishing a trusting relationship and empowering the patient during the examination, rather than solely aiding in identifying questions or areas needing education.
