Nursing Elites

1. Nurses should understand the chain of infection because it refers to:

• A. the linkages involved in disease transmission.
• B. the sequence required for transmission of disease.
• C. the clustering of bacteria in a specific pattern.
• D. increasing virulence patterns among microorganisms.

Correct answer: B

Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures. Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection. Choice A is too broad and does not specifically address the sequential nature of disease transmission. Choice C focuses on bacterial clustering rather than the transmission process. Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.

2. While assessing a patient in the ICU, a nurse observes signs of a weak pulse, quick respiration, acetone breath, and nausea. Which of the following conditions is most likely occurring?

• A. Hypoglycemic patient
• B. Hyperglycemic patient
• C. Cardiac arrest
• D. End-stage renal failure

Correct answer: B

Rationale: The correct answer is a hyperglycemic patient. The signs described - weak pulse, quick respiration, acetone breath, and nausea - are indicative of hyperglycemia. A hypoglycemic patient would typically present with different signs such as pale skin, sweating, and confusion. Cardiac arrest would manifest with sudden loss of heart function and consciousness, not the signs described. End-stage renal failure would present with symptoms related to kidney dysfunction like edema, fatigue, and changes in urine output, which are not mentioned in the scenario.

3. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

4. A one-month-old infant in the neonatal intensive care unit is dying. The parents request that the nurse administer an opioid analgesic to their infant, who is crying weakly. The infant's heart rate is 68 beats per minute, and the respiratory rate is 18 breaths per minute. The infant is on room air, and the oxygen saturation is 92%. The nurse's response is based on which of the following principles?

• A. Providing analgesia during the last days and hours is an ethically appropriate nursing action.
• B. Withholding the opioid analgesia during the last days and hours is an ethical duty because administering it would represent assisted suicide.
• C. Administering analgesia during the last days and hours is the parents' ethical decision.
• D. Withholding the opioid analgesia is clinically appropriate because it will hasten the infant's death.

Correct answer: A

Rationale: All patients, regardless of age, have the right to die with dignity and be free from pain. In this case, the parents' request for an opioid analgesic to relieve the child's distress aligns with the principles of palliative care and ensuring comfort. Assisted suicide involves a conscious decision by the individual, which is not applicable to a 1-month-old infant. Both the nurse and the parents have an ethical duty to ensure the infant's comfort and well-being. Withholding opioid analgesia solely to hasten death is not appropriate, as providing pain relief is a crucial aspect of end-of-life care. Opioids can be administered to dying patients at any age to alleviate suffering without the intention of hastening death. Therefore, providing analgesia during the last days and hours is an ethically appropriate nursing action. Choices B, C, and D are incorrect because the decision to administer analgesia in this scenario is based on the best interest and comfort of the infant, not concerns about assisted suicide or hastening death. The ethical consideration is to provide compassionate care and alleviate suffering.

5. A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?

• A. cold, burning, aching, and numbness
• B. burning, aching, cold, and numbness
• C. aching, cold, burning, and numbness
• D. cold, aching, burning, and numbness

Correct answer: A

Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.
