What are the side effects of first-generation over-the-counter (OTC) antihistamines like diphenhydramine (Benadryl) and hydroxyzine (Atarax) in infants and children?
- A. Reye's syndrome.
- B. cholinergic effects.
- C. paradoxical CNS stimulation.
- D. nausea and diarrhea.
Correct Answer: C
Rationale: The correct answer is paradoxical CNS stimulation. First-generation OTC antihistamines, such as diphenhydramine and hydroxyzine, can lead to paradoxical CNS stimulation in infants and children. This phenomenon is characterized by symptoms like excitement, euphoria, restlessness, and confusion, rather than the expected sedative effect. Due to this unexpected response, these antihistamines are used less frequently in pediatric populations. Reye's syndrome is a rare systemic response to a virus and is not a side effect of antihistamines. First-generation OTC antihistamines do not typically exhibit cholinergic effects. Nausea and diarrhea are uncommon side effects of these antihistamines and are less commonly observed than paradoxical CNS stimulation.

The client with peripheral vascular disease is reviewing self-care measures. Which of the following statements indicates proper self-care measures?
- A. "I like to soak my feet in the hot tub every day."?
- B. "I walk to the mailbox in my bare feet."?
- C. "I stopped smoking and only use chewing tobacco."?
- D. "I have my wife examine the soles of my feet each day."?
Correct Answer: D
Rationale: The correct answer is, "I have my wife examine the soles of my feet each day."? Clients with peripheral vascular disease should examine their feet daily for any signs of redness, dryness, or cuts. If the client is unable to do this themselves due to decreased sensation in their feet, a caregiver or family member should assist. Soaking feet in a hot tub should be avoided as the client may not be able to sense if the water is too hot, potentially causing burns. Walking barefoot can lead to injuries, so wearing shoes or slippers is recommended to minimize trauma. While quitting smoking is a positive step, using chewing tobacco can still constrict blood vessels, adversely affecting circulation in the extremities.
The death of a beloved spouse places the surviving partner in which type of crisis?
- A. maturational
- B. reactive
- C. nonreactive
- D. situational
Correct Answer: D
Rationale: The correct answer is 'situational.' A situational crisis is an unexpected, unplanned event, such as the death of a spouse, which can lead to significant distress. Option A is incorrect because a maturational crisis is related to normal life transitions like getting married or retiring. Choices B and C are incorrect as they do not represent recognized crisis states in the context of the scenario provided.
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 that can be used to relieve nausea and vomiting. Ondansetron (Zofran) works by blocking serotonin receptors in the chemoreceptor trigger zone (CTZ) and the gastrointestinal tract. This action helps reduce nausea and vomiting. Metoclopramide (Reglan) works as a dopamine antagonist and also has prokinetic effects, making it effective for different conditions. Hydroxyzine (Vistaril) is an antihistamine with antiemetic properties, but it does not act as a serotonin antagonist. Prochlorperazine (Compazine) is a dopamine antagonist that is also used to treat nausea and vomiting, but not as a serotonin antagonist like ondansetron.
The client is scheduled for surgical repair of a detached retina. What is the most likely preoperative nursing diagnosis for this client?
- A. Anxiety related to loss of vision and potential failure to regain vision.
- B. Deficient knowledge (preoperative and postoperative activities) related to lack of information.
- C. Acute pain related to tissue injury and decreased circulation to the eye.
- D. Risk for infection related to the eye injury.
Correct Answer: A
Rationale: The correct preoperative nursing diagnosis for a client scheduled for surgical repair of a detached retina is 'Anxiety related to loss of vision and potential failure to regain vision.' A client facing the threat of permanent blindness due to a detached retina is likely to experience anxiety. Addressing this anxiety is crucial before providing education, as severe anxiety can hinder the client's ability to absorb new information. The nurse should offer emotional support, encourage the client to express concerns, and clarify any misconceptions. Acute pain is not a typical symptom of a detached retina, and the risk of infection preoperatively is minimal, making choices C and D less relevant in this scenario.
A nurse is taking the health history of an 85-year-old client. Which of the following physical findings is consistent with normal aging?
- A. Increase in subcutaneous fat.
- B. Diminished cough reflex.
- C. Long-term memory loss.
- D. Myopia.
Correct Answer: B
Rationale: The correct answer is 'Diminished cough reflex.' Diminished cough reflex is a physical finding consistent with normal aging in older adults, which can increase the risk of aspiration and atelectasis. An increase in subcutaneous fat actually raises the risk of pressure ulcers. While long-term memory is typically preserved in aging unless affected by dementia, short-term memory often declines. Myopia (near-sightedness) is common in younger individuals, but presbyopia (far-sightedness) is more common with aging. Additionally, individuals with myopia may experience an improvement in vision as they age.
