A nurse is preparing to teach a client about the use of a peak flow meter. Which of the following instructions should the nurse include?
- A. Place the mouthpiece in your mouth and blow out as quickly as you can.
- B. Exhale slowly into the mouthpiece over 5 seconds.
- C. Take a slow deep breath before blowing into the mouthpiece.
- D. Blow into the mouthpiece at a steady rate for 3 seconds.
Correct Answer: A
Rationale: The correct instruction for using a peak flow meter is to place the mouthpiece in your mouth and blow out as quickly as you can. This action helps measure the peak expiratory flow of the client. Choice B is incorrect because exhaling slowly does not provide an accurate peak flow reading. Choice C is incorrect as taking a slow deep breath before blowing interferes with obtaining an accurate measurement. Choice D is incorrect as blowing at a steady rate for 3 seconds may not reflect the peak expiratory flow accurately.

A nurse is preparing to assess a 2-week-old newborn. Which of the following actions should the nurse plan to take?
- A. Obtain the newborn's body temperature using a tympanic thermometer
- B. Pull the pinna of the infant's ear forward before inserting the probe
- C. Auscultate the newborn's apical pulse for 60 seconds
- D. Measure the newborn's head circumference over the eyebrows and below the occipital prominence
Correct Answer: C
Rationale: The correct answer is C: Auscultate the newborn's apical pulse for 60 seconds. When assessing a newborn, it is essential to auscultate the apical pulse for a full 60 seconds to accurately determine their heart rate. This method allows for a more precise measurement, considering the variability in heart rates in newborns. Choice A is incorrect because tympanic thermometers are not typically used for newborns due to their ear canals being small and not fully developed. Choice B is incorrect as pulling the pinna forward is not necessary for assessing the apical pulse. Choice D is incorrect as measuring head circumference involves a different assessment and is not relevant to determining the heart rate of a newborn.
A nurse is assessing a client who has a chest tube. Which of the following findings should the nurse report to the provider?
- A. Constant bubbling in the water seal chamber.
- B. Intermittent bubbling in the suction control chamber.
- C. Tidaling in the water seal chamber.
- D. Drainage of 75 mL in the first 24 hours.
Correct Answer: A
Rationale: The correct answer is A: Constant bubbling in the water seal chamber. Constant bubbling in the water seal chamber can indicate an air leak, which compromises the integrity of the chest tube system and should be reported to the provider for immediate intervention. Choices B, C, and D are incorrect. Intermittent bubbling in the suction control chamber is an expected finding indicating that the system is working appropriately. Tidaling in the water seal chamber is a normal fluctuation of fluid level with inspiration and expiration, indicating that the system is functioning correctly. Drainage of 75 mL in the first 24 hours is within the expected range for chest tube drainage and does not require immediate reporting unless accompanied by other concerning symptoms.
A nurse is caring for a client who is 1 day postoperative following a total knee replacement. The client reports pain of 8 on a scale of 0 to 10. Which of the following actions should the nurse take?
- A. Administer ibuprofen 400 mg PO
- B. Administer oxycodone 10 mg PO
- C. Reposition the client to the unaffected side
- D. Apply a cold compress to the affected knee
Correct Answer: B
Rationale: In this scenario, the appropriate action for the nurse to take when a client reports severe postoperative pain of 8 out of 10 is to administer oxycodone 10 mg PO. Oxycodone is a potent analgesic that is more effective in managing severe pain compared to ibuprofen, making choice A incorrect. Repositioning the client to the unaffected side or applying a cold compress may provide some comfort but are not the priority interventions for severe postoperative pain, making choices C and D less appropriate.
A nurse is admitting a client who has schizophrenia and experiences auditory hallucinations. The client states, 'It's hard not to listen to the voices.' Which of the following questions should the nurse ask?
- A. Do you understand that the voices are not real?
- B. Why do you think the voices are talking to you?
- C. Have you tried going to a private place when this occurs?
- D. What helps you ignore what you are hearing?
Correct Answer: D
Rationale: The correct answer is 'D: What helps you ignore what you are hearing?' Asking the client about coping mechanisms is essential in assisting them to manage auditory hallucinations. Choice A is incorrect as questioning the reality of the voices may not be helpful. Choice B delves into the cause of the hallucinations rather than coping strategies. Choice C focuses on isolation rather than addressing the client's coping mechanisms.
A nurse is assessing a client who is receiving magnesium sulfate for preeclampsia. Which of the following findings should the nurse report to the provider?
- A. Respiratory rate 16/min.
- B. Blood pressure 118/78 mm Hg.
- C. Urinary output of 30 mL/hr.
- D. Absent deep-tendon reflexes.
Correct Answer: D
Rationale: The correct answer is D. Absent deep-tendon reflexes indicate magnesium toxicity and should be reported immediately. Magnesium sulfate is used to prevent seizures in clients with preeclampsia, but toxicity can lead to serious complications, including respiratory depression and loss of deep-tendon reflexes. Choices A, B, and C are within normal limits and expected findings in a client receiving magnesium sulfate for preeclampsia, so they do not require immediate reporting.
