1. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?
- A. Apical heart rate of 60 beats/min
- B. Sweating across the forehead
- C. Poor sucking effort
- D. Respiratory rate of 30 breaths/min
Correct answer: A
Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.
2. A client with a diagnosis of schizophrenia is experiencing auditory hallucinations. What is the most appropriate nursing intervention?
- A. Ask the client to describe the voices and what they are saying.
- B. Tell the client that the voices are not real.
- C. Encourage the client to engage in reality-based activities.
- D. Ask the client to focus on positive thoughts instead of the voices.
Correct answer: C
Rationale: The most appropriate nursing intervention for a client with schizophrenia experiencing auditory hallucinations is to encourage them to engage in reality-based activities. This intervention helps manage auditory hallucinations by redirecting the client's focus away from the hallucinations. Choice A is not recommended as it may exacerbate the hallucinations or distress the client. Choice B is incorrect because denying the reality of the voices can invalidate the client's experiences. Choice D, asking the client to focus on positive thoughts, may not be effective in addressing the auditory hallucinations directly.
3. The nurse is planning discharge teaching for four mothers. Which postpartum client is at highest risk for psychological difficulties during the postpartum period?
- A. A primiparous woman who has recently migrated to the US with her spouse
- B. A multiparous client who lives with her husband and his family members
- C. A multiparous female with a large family living in a community
- D. A primiparous adolescent living at home with her parents and significant other
Correct answer: A
Rationale: A primiparous woman who has recently migrated to the US with her spouse is at the highest risk for psychological difficulties during the postpartum period. Recent migration and adjustment to a new environment can increase the risk of postpartum depression, especially when combined with the challenges of being a new mother. Choice B, a multiparous client living with her husband and his family, may have social support from family members, which can be protective against psychological difficulties. Choice C, a multiparous female with a large family living in a community, also indicates potential social support. Choice D, a primiparous adolescent living at home with her parents and significant other, may have a support system in place with her family and significant other.
4. What is a common sign of a respiratory infection in infants?
- A. Increased appetite
- B. Rapid breathing
- C. Decreased urine output
- D. Lethargy
Correct answer: B
Rationale: Rapid breathing is a common sign of a respiratory infection in infants. When infants have a respiratory infection, their breathing may become rapid as their body tries to get more oxygen. This symptom is often seen alongside cough and fever. Increased appetite (Choice A) is not typically associated with respiratory infections but can be seen in other conditions. Decreased urine output (Choice C) is more indicative of dehydration or kidney issues rather than a respiratory infection. Lethargy (Choice D) can be a symptom of various illnesses but is not as specific to respiratory infections as rapid breathing.
5. A female client is brought to the emergency department after police officers found her disoriented, disorganized, and confused. The RN also determines that the client is homeless and is exhibiting suspiciousness. The client's plan of care should include what priority problem?
- A. Acute confusion.
- B. Ineffective community coping.
- C. Disturbed sensory perception.
- D. Self-care deficit.
Correct answer: A
Rationale: Acute confusion is the priority problem as it directly affects the client's ability to process information and make safe decisions. In this scenario, the client's disorientation, disorganization, and confusion indicate an immediate cognitive issue that requires attention to ensure her safety and stability. Choices B, C, and D are not the priority problems in this case. Ineffective community coping, disturbed sensory perception, and self-care deficit, while important, are secondary to the client's acute confusion, which poses an immediate risk to her well-being.
