When assessing a patient's feet, the nurse notices that the toenails are thick and separated from the nail bed. What does the nurse most likely suspect is the cause of this condition?

Correct Answer: A

Rationale: The nurse would most likely suspect fungi as the cause of thickened and separated toenails. Fungal infections can lead to changes in the nail structure, causing them to thicken and separate from the nail bed. Friction, nail polish, and nail polish remover are less likely to cause these specific nail changes. Friction typically leads to calluses or blisters, while nail polish and nail polish remover do not commonly result in thickened and separated toenails.

Correct Answer: B

Rationale: The correct action for the nurse to take is to give information about advance directives to the client. By providing this information, the nurse empowers the client to make an informed decision about their care preferences. Choice A is incorrect because simply recording the lack of advance directive does not address the client's need for information. Choice C is incorrect because assuming the client wishes a full code without discussing it with them is not appropriate and may not align with the client's wishes. Choice D is incorrect as the nurse should directly address the issue with the client rather than involving another staff member.

Correct Answer: C

Rationale: The correct immediate action for a healthcare worker who has been stuck by an exposed needle is to wash the hands thoroughly with soap and water to reduce the risk of infection. This helps to remove any potential pathogens introduced by the needle stick. Looking up the policy on needle sticks (Choice A) is important but not the immediate action required. Contacting employee health services (Choice B) and notifying the supervisor and risk management (Choice D) are crucial steps to take, but they should follow the initial step of washing the hands to mitigate the risk of infection.

Correct Answer: A

Rationale: The correct answer is A: Pain related to ischemia. This nursing diagnosis should have priority because addressing the pain caused by ischemia is crucial in managing the client's myocardial infarction. Pain management is essential not only for the client's comfort but also for improving outcomes and reducing complications. Choices B, C, and D are not the priority in this scenario. Risk for altered elimination: constipation (Choice B) is not as immediate a concern as managing the client's pain. Risk for complication: dysrhythmias (Choice C) may be a potential concern but addressing the client's pain takes precedence. Anxiety related to pain (Choice D) is important to address but should come after managing the pain itself.

Correct Answer: D

Rationale: The correct answer is D. Whitish oval specks sticking to the hair shaft are nits, which are a definitive sign of pediculosis capitis (head lice). A: Scratching the head more than usual is a common symptom but not confirmatory of head lice infestation. B: Flakes evident on a student's shoulders may indicate dandruff or dry scalp, not necessarily head lice. C: Oval pattern occipital hair loss is not a typical manifestation of pediculosis capitis.
