ATI Comprehensive Predictor PN

Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.

Correct Answer: B

Rationale: The correct first step in preparing a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to ensure compatibility and prevent adverse reactions. Administering the blood via IV push (Choice A) is incorrect as it skips the essential step of verifying the blood type. Warming the blood to body temperature (Choice C) is important but comes after verifying the blood type. Administering diuretics (Choice D) is not part of the preparation process for a blood transfusion.

Correct Answer: B

Rationale: The axillary method is the most appropriate for newborns because it is non-invasive and safe. Rectal temperature measurement can be uncomfortable and poses a risk of injury, especially in newborns. Oral temperature measurement is not recommended for newborns due to their inability to cooperate and potential inaccuracies. Tympanic temperature measurement may not be as accurate in newborns compared to older children or adults.

Correct Answer: B

Rationale: Hypervigilance is a common manifestation of PTSD characterized by heightened alertness and fear of danger. This heightened state of awareness can lead to irritability, difficulty concentrating, and sleep disturbances. Choices A, C, and D are incorrect. Hyperactivity is not typically associated with PTSD; restlessness may be present but is not the primary manifestation, and avoidance of social situations is more commonly seen in conditions like social anxiety disorder rather than PTSD.

Correct Answer: B

Rationale: The best strategy for managing dehydration in a client is to monitor fluid and electrolyte levels frequently. This allows healthcare providers to assess the client's hydration status accurately and make informed decisions regarding treatment. Encouraging the client to drink more water (Choice A) may not be sufficient if the dehydration is severe and requires specific interventions. Administering oral rehydration solutions (Choice C) can be beneficial but should be guided by monitoring the client's condition. Increasing the IV fluid rate (Choice D) may be necessary in certain cases, but it is not always the initial or best approach, as monitoring is crucial to avoid fluid and electrolyte imbalances.
