Which of the following manifestations confirms the presence of pediculosis capitis in students?

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: B

Rationale: The correct action for the nurse to take when measuring a client's oral temperature using an electronic thermometer is to inquire whether the client has smoked in the last 30 minutes. Smoking can affect the accuracy of oral temperature readings. Providing oral hygiene (Choice A) is not directly related to ensuring accurate temperature measurement. Connecting the red tip probe (Choice C) is not specific to oral temperature measurement accuracy. Positioning the probe tip against the buccal mucosa (Choice D) is incorrect as oral temperature is typically measured under the tongue, not against the cheek.

Correct Answer: D

Rationale: The correct answer is D: Supervisor. In this scenario, the nurse manager is acting as a supervisor to oversee and ensure the newly licensed nurse performs the straight catheterization correctly, following protocols, and maintaining client safety. A supervisor role involves monitoring and guiding staff in their duties to ensure quality care. Choices A, B, and C are incorrect. A case manager typically manages a case load of clients but does not provide direct care like in this situation. Client educator and client advocate roles do not directly relate to supervising or overseeing a procedure being performed by another nurse.

Correct Answer: B

Rationale: The correct action for the healthcare provider when providing discharge teaching to a client who does not speak the same language is to offer written instructions in the client's language. This approach helps ensure better comprehension and adherence to the instructions as the client can refer back to the written material for clarification. Choice A is incorrect because using proper medical terms may not be effective if the client does not understand the language. Choice C is incorrect since verbal instructions should be directed to the client for better understanding. Choice D is incorrect as assistive personnel may not be qualified or trained to provide accurate interpretation, risking miscommunication and potential errors in the instructions.

Correct Answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

Correct Answer: A

Rationale: When caring for a client with a tracheostomy, the nurse should clean the skin around the stoma with normal saline to prevent infection and ensure cleanliness. This action helps in maintaining skin integrity and preventing skin breakdown. Securing the tracheostomy ties with two fingers' width underneath is essential to allow for proper fit, prevent skin irritation, and ensure the ties are not too tight. Soaking the outer cannula in warm tap water is not recommended as it can lead to contamination and is not a standard practice. Using a cotton tip applicator to clean the inside of the inner cannula is discouraged as it can leave fibers behind, increasing the risk of aspiration and respiratory complications.

Correct Answer: A

Rationale: During a standing assessment, the healthcare professional should observe the patient laterally. In a normal body alignment, the head is erect, and the spinal curves align in a reversed 'S' pattern, aiding in maintaining balance and posture. Choice B is incorrect because hips and shoulders should be level and not form an 'S' pattern when observed posteriorly. Choice C is incorrect as the position of the arms is not a key indicator of body alignment. Choice D is incorrect as the feet should be shoulder-width apart with toes pointing forward for optimal balance and stability.

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: B

Rationale: The correct answer is to emphasize emptying the child's mouth in any case of possible poisoning. This action is crucial to prevent further ingestion of the poisonous substance. Choice A is incorrect because calling the Poison Control Center should be one of the first steps, not waiting until the situation is identified. Choice C is incorrect as moving the child may spread or exacerbate the effects of the toxic substance. Choice D is incorrect because inducing vomiting can be harmful if the poison is a hydrocarbon, as it may lead to aspiration.
