1. A client is admitted to the labor and delivery unit in early labor, and the nurse assesses the status of her contractions. The frequency of contractions is most accurately evaluated by counting the minutes and seconds in which manner?
- A. From the peak of one contraction to the peak of the next contraction
- B. From the beginning of one contraction to the end of that contraction
- C. From the beginning of one contraction to the beginning of the next contraction
- D. From the end of one contraction to the beginning of the next contraction
Correct answer: C
Rationale: The frequency of contractions is measured from the beginning of one contraction to the beginning of the next contraction. This timing is crucial in determining the progress of labor. Choice A, measuring from peak to peak, is incorrect as it assesses the duration between the highest points of contractions, which is not how frequency is calculated. Choice B, measuring from the beginning to the end of one contraction, is incorrect as it does not consider the start of the next contraction. Choice D, measuring from the end of one contraction to the beginning of the next contraction, is incorrect as it misses the initial onset of the following contraction.
2. When implementing a disaster intervention plan, which intervention should the nurse implement first?
- A. Initiate the discharge of stable clients from hospital units
- B. Identify a command center where activities are coordinated
- C. Assess community safety needs impacted by the disaster
- D. Instruct all essential off-duty personnel to report to the facility
Correct answer: B
Rationale: When implementing a disaster intervention plan, the first step the nurse should take is to identify a command center where activities are coordinated. This step is crucial for ensuring an organized and effective disaster response. Option A, initiating the discharge of stable clients, is not a priority during the initial phase of disaster response. Option C, assessing community safety needs, usually follows setting up a command center. Option D, instructing off-duty personnel to report, may be necessary but is not the primary intervention at the beginning of a disaster situation.
3. The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?
- A. Inflammation of the mucous membrane & bronchospasm
- B. Increased mucus production and bronchoconstriction
- C. Allergic reactions and hyperventilation
- D. Airway narrowing and decreased lung capacity
Correct answer: A
Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.
4. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse’s decision to hold the client’s scheduled antihypertensive medication?
- A. Increased urinary clearance of the multiple medications has led to diuresis and lowered the blood pressure.
- B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness.
- C. The additive effect of multiple medications has caused the blood pressure to drop too low.
- D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.
Correct answer: C
Rationale: The correct answer is C. When a client experiences syncope due to a significant drop in blood pressure after receiving multiple antihypertensive medications, the additive effect of these medications can cause the blood pressure to drop excessively. This additive effect can lead to hypotension, which is why the nurse decided to hold the client's scheduled antihypertensive medication. Choices A, B, and D provide incorrect rationales. Choice A mentions diuresis, which is not directly related to the drop in blood pressure due to additive medication effects. Choice B refers to an antagonistic interaction reducing effectiveness, which is not applicable in this scenario. Choice D talks about a synergistic effect leading to drug toxicity, which is not the cause of the sudden drop in blood pressure observed in the client.
5. To evaluate the medication’s effectiveness in a client with a respiratory tract infection, which laboratory values should the nurse monitor?
- A. White blood cell (WBC) count
- B. Sputum culture and sensitivity
- C. Droplet precautions
- D. Protective environment
Correct answer: A
Rationale: The correct answer is A: White blood cell (WBC) count. Monitoring the WBC count helps assess the overall response to infection and the effectiveness of the antibiotic. Sputum culture and sensitivity (choice B) are also important to confirm if the antibiotic is targeting the specific pathogen. Choices C and D, droplet precautions and protective environment, are not laboratory values but rather infection control measures that do not directly evaluate the medication's effectiveness in treating the infection.
