Correct Answer: B

Rationale: Drug overdose is the most common method of attempted suicide. While hanging, gunshot, and slashing the wrists are also methods used in suicide attempts, statistics show that drug overdose is the most prevalent method chosen by individuals attempting suicide. Hanging, gunshot, and slashing the wrists are indeed common methods as well, but drug overdose ranks highest in terms of frequency.

Correct Answer: B

Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.

Correct Answer: D

Rationale: Placing warm blankets next to the client's feet is the most appropriate action to provide warmth and comfort. This method is safe and effective in addressing the client's complaint of uncomfortably cool feet at night. Providing a warming pad (Choice A) may pose a risk of burns or injury, especially for a client with decreased sensation due to diabetes. Mediating the client with a sedative (Choice B) does not address the underlying issue of cool feet and may not be necessary. Using a bed cradle (Choice C) to hold the covers off the feet does not directly address the client's need for warmth and comfort.

Correct Answer: D

Rationale: In this scenario, the patient is a young adult male with type 2 diabetes mellitus admitted for a hernia repair who is experiencing weakness and jitteriness. Checking his fingerstick glucose is crucial to assess his blood sugar levels, which can directly impact his symptoms. Assessing his skin temperature and moisture is important to evaluate his peripheral circulation and hydration status. Measuring his pulse and blood pressure helps in gauging his cardiovascular status. Therefore, all the actions mentioned in choices A, B, and C are appropriate for the nurse to implement in this situation to identify the underlying cause of the patient's symptoms. Choice D, 'All of the Above,' is the correct answer because all these actions are necessary for a comprehensive assessment of the patient's condition. Choices A, B, and C are incorrect individually as they each address different aspects of the patient's condition, and a holistic approach is needed to provide optimal care in this situation.

Correct Answer: D

Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.
