1. An adult male was diagnosed with stage IV lung cancer three weeks ago. His wife approaches the nurse and asks how she will know that her husband's death is imminent because their two adult children want to be there when he dies. What is the best response by the nurse?
- A. Explain that the client will start to lose consciousness and his body systems will slow down
- B. Reassure the spouse that the healthcare provider will let her know when to call the children
- C. Offer to discuss the client’s health status with each of the adult children
- D. Gather information on how long it will take for the children to arrive
Correct answer: A
Rationale: The best response for the nurse is to explain that the client will start to lose consciousness and his body systems will slow down. Providing information on the signs of impending death helps the family prepare emotionally and allows them to be present at the appropriate time. Choice B is incorrect because it does not empower the family with the knowledge they seek. Choice C is incorrect as discussing the client’s health status individually with the adult children may not address the wife's immediate concern. Choice D is incorrect as the priority should be on preparing the family for the signs of imminent death rather than focusing on logistical details.
2. Which is the most important safety measure when administering a medication through a patient’s central venous catheter (CVC)?
- A. Using a sterile technique
- B. Ensuring correct placement of the CVC
- C. Flushing the CVC with saline after administration
- D. Monitoring for signs of infection
Correct answer: B
Rationale: The most important safety measure when administering a medication through a patient’s central venous catheter (CVC) is ensuring the correct placement of the CVC. This is crucial to prevent complications such as extravasation, infection, or improper drug delivery. While using a sterile technique, flushing the CVC with saline after administration, and monitoring for signs of infection are all important aspects of CVC care, ensuring the correct placement of the catheter takes precedence as it directly impacts patient safety during medication administration.
3. Do dizygotic (DZ) twins run in families?
- A. Yes
- B. No
- C. Rarely
- D. Never
Correct answer: A
Rationale: Yes, dizygotic (DZ) twins can run in families. This is due to genetic factors that influence hyperovulation, where a woman releases multiple eggs during her menstrual cycle. This genetic predisposition can be passed down through generations, increasing the likelihood of having dizygotic twins. Choices B, C, and D are incorrect because the statement that dizygotic twins run in families is true, as supported by scientific evidence. It is important to note that while the genetic predisposition for dizygotic twins can run in families, it does not guarantee that every generation will have twins, as other factors also play a role in twin pregnancies.
4. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?
- A. Parathyroid hormone
- B. Insulin
- C. Cortisol
- D. Thyroxine
Correct answer: A
Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.
5. Parents of a sick infant talk with a nurse about their baby. One parent says, “I am so upset; I didn’t realize our baby was ill.” What major indication of illness in an infant should the nurse explain to the parent?
- A. Grunting respirations
- B. Excessive perspiration
- C. Longer periods of sleep
- D. Crying immediately after feedings
Correct answer: C
Rationale: The correct answer is C. Longer periods of sleep than usual can be a sign of illness in infants. When an infant sleeps more than usual, it can indicate that the baby is conserving energy due to an underlying condition. Grunting respirations (choice A) can be a sign of respiratory distress, not just an indication of illness. Excessive perspiration (choice B) can occur due to various reasons and is not a specific major indication of illness. Crying immediately after feedings (choice D) is a common behavior in infants and not necessarily a major indication of illness.
