1. What is one characteristic of human immunodeficiency virus (HIV)?
- A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
- B. HIV replication occurs intracellularly.
- C. HIV integrates its genetic material into the host cell's DNA.
- D. DNA replication is irrelevant to HIV.
Correct answer: C
Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.
2. The factor that most determines drug distribution is:
- A. vascular perfusion of the tissue or organ.
- B. salt form.
- C. drug interactions.
- D. steady state.
Correct answer: A
Rationale: The correct answer is 'vascular perfusion of the tissue or organ.' Drug distribution is primarily determined by how well the circulatory system delivers the drug to various tissues and organs. Adequate perfusion ensures proper distribution of the drug throughout the body. While the salt form (choice B), drug interactions (choice C), and steady state (choice D) can influence drug efficacy and metabolism, they are not as crucial as vascular perfusion for the initial distribution of a drug.
3. 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.
4. When auscultating breath sounds, the nurse auscultates over the following locations:
- A. Trachea and lateral areas of thoracic cage
- B. Anterior and posterior aspects of all lung fields
- C. The mid section as well as the lateral section of the lungs
- D. The mid-clavicular to mid-axillary lines comparing side to side
Correct answer: B
Rationale: The correct answer is B: Anterior and posterior aspects of all lung fields. When auscultating breath sounds, it is essential to listen to the front (anterior) and back (posterior) aspects of all lung fields. This comprehensive approach allows for a thorough assessment of breath sounds throughout the lungs. Choices A, C, and D are incorrect. Choice A is too limited as it only focuses on the trachea and lateral areas, not covering all lung fields. Choice C is also too limited, referring to specific sections of the lungs (mid section and lateral section). Choice D is incorrect as it suggests comparing specific lines on the chest (mid-clavicular to mid-axillary), which is not a standard practice for auscultating breath sounds.
5. A patient has suffered a left CVA and developed severe hemiparesis resulting in a loss of mobility. The nurse notices on assessment that an area over the patient's left elbow appears as non-blanchable erythema, and the skin is intact. The nurse should score the patient as having which of the following?
- A. Stage I pressure ulcer
- B. Stage II pressure ulcer
- C. Stage III pressure ulcer
- D. Stage IV pressure ulcer
Correct answer: A
Rationale: Erythema with the skin intact is characteristic of a Stage I pressure ulcer. At this stage, the skin is not broken, but there is localized redness that does not blanch when pressed. Stage II pressure ulcers involve partial-thickness skin loss, Stage III pressure ulcers have full-thickness skin loss, and Stage IV pressure ulcers extend to deeper tissues, including muscle and bone. In this case, the non-blanchable erythema with intact skin aligns with the characteristics of a Stage I pressure ulcer.
