1. 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.
2. A client with heart failure is receiving digoxin. Which of the following findings should the nurse report to the provider?
- A. Heart rate of 78/min.
- B. Vision changes.
- C. Respiratory rate of 16/min.
- D. Blood pressure of 120/80 mm Hg.
Correct answer: B
Rationale: The correct answer is B: Vision changes. Vision changes are a classic sign of digoxin toxicity and should be reported immediately to the provider for further evaluation and management. A heart rate of 78/min, a respiratory rate of 16/min, and a blood pressure of 120/80 mm Hg are within normal ranges and are not typically associated with digoxin toxicity. Therefore, they would not be the priority findings to report in this situation.
3. A healthcare provider is caring for a client who has been diagnosed with sepsis. Which of the following laboratory results indicates that the client is developing disseminated intravascular coagulation (DIC)?
- A. Elevated hemoglobin
- B. Elevated white blood cell count
- C. Decreased fibrinogen level
- D. Decreased platelet count
Correct answer: D
Rationale: The correct answer is D, decreased platelet count. In disseminated intravascular coagulation (DIC), there is widespread activation of clotting factors leading to the formation of multiple blood clots throughout the body, which can deplete platelets. A decreased platelet count is a hallmark of DIC. Elevated hemoglobin (choice A) and elevated white blood cell count (choice B) are not specific indicators of DIC. While fibrinogen levels (choice C) can be decreased in DIC due to consumption, a decreased platelet count is a more specific and early sign of DIC development.
4. A charge nurse is teaching a group of nurses about the correct use of restraints. Which of the following should the nurse include in the teaching?
- A. Place a belt restraint on a school-age child who has seizures.
- B. Secure wrist restraints to the bed rails for an adolescent.
- C. Apply elbow immobilizers to an infant with a cleft lip injury.
- D. Keep the side rails of a toddler's crib elevated.
Correct answer: D
Rationale: The correct use of restraints is crucial to ensure patient safety. Keeping the side rails of a toddler's crib elevated is a safe practice as it prevents falls and provides a level of protection without directly restraining the child. Placing a belt restraint on a child with seizures (Choice A) is inappropriate as it may restrict movement and cause harm during a seizure. Securing wrist restraints to bed rails for an adolescent (Choice B) is not recommended as it can lead to injuries and compromise circulation. Applying elbow immobilizers to an infant with a cleft lip injury (Choice C) is also incorrect as it does not address the issue of restraint and is not a standard practice in this situation.
5. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?
- A. PaO2 of 95 mm Hg
- B. PaCO2 of 55 mm Hg
- C. HCO3 of 24 mEq/L
- D. pH level of 7.35
Correct answer: B
Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.
