The nurse is caring for an older adult patient diagnosed with Alzheimer's disease who is ambulatory but requires total assistance with activities of daily living (ADLs). The nurse notices that the patient is edentulous. Which area should the nurse assess?

Correct Answer: A

Rationale: The correct answer is to assess the oral cavity. 'Edentulous' means without teeth, so the nurse should assess the oral cavity for any issues related to oral health, dentures, or potential complications. This assessment is crucial to prevent oral health problems and ensure proper care for the patient. Assessing the room for drafts (choice B) is unrelated to the patient's edentulous status and does not address the immediate care needs. Assessing ankles for edema (choice C) is important for circulatory assessment but not directly related to the patient being edentulous. Assessing for reduced sensations (choice D) would be more relevant for neurological or sensory concerns, which are not specifically associated with being edentulous.

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.

Correct Answer: C

Rationale: The correct answer is C. Telangiectatic nevi, often referred to as 'stork bites,' are common birthmarks in infants and are considered normal. These birthmarks usually fade and disappear as the child grows older. Choices A, B, and D are incorrect because Mongolian spots are bluish-gray birthmarks commonly found in darker-skinned infants, port wine stains are vascular birthmarks that typically do not disappear, and surgical removal is not recommended for telangiectatic nevi as they usually resolve on their own.
