nclex physical and health assessment questions

Correct Answer: D

Rationale: The correct answer is D: Second-hand cigarette smoke. Exposure to second-hand smoke can irritate and inflame the lining of the Eustachian tube, making young children more susceptible to ear infections. This is supported by research showing a clear link between exposure to cigarette smoke and increased rates of ear infections in children. Family history (A) may contribute to genetic predisposition but is not a direct risk factor. Air conditioning (B) does not directly cause ear infections. Excessive cerumen (C) can lead to blockages but is not a primary risk factor for infections.

Correct Answer: D

Rationale: The correct answer is D because using the index and middle fingers to palpate with gentle pressure in a rotating pattern allows for a thorough examination of the lymph nodes without causing discomfort or injury. This method helps to assess the size, shape, consistency, and tenderness of the nodes accurately. It also enables the examiner to detect any abnormalities such as enlargement or tenderness. A is incorrect as using strong pressure can be painful and lead to inaccurate assessment. B is incorrect as strong pressure can be harmful and may not provide the necessary sensitivity to detect abnormalities. C is incorrect as pinching each node can be uncomfortable and may not allow for a systematic examination of the lymph nodes.

Correct Answer: A

Rationale: The correct answer is A: An optic disc that is a yellow-orange colour. This is a normal finding because the optic disc typically appears yellow-orange due to the presence of nerve fibers. The yellow-orange color is due to the absence of blood vessels in this area. This is a normal anatomical characteristic of the optic disc. Option B is incorrect because blurred optic disc margins can indicate pathology such as papilledema. Option C is incorrect because the presence of pigmented crescents in the macular area can indicate a condition like myopic degeneration, not a normal finding. Option D is incorrect because the macula is normally located temporally, not nasally, to the optic disc.

Correct Answer: D

Rationale: The correct answer is D: "Prolonged use of a bottle can increase the risk for tooth decay and ear infections." This response is the best because it addresses the potential consequences of prolonged bottle use, which include tooth decay and ear infections. It educates the mother on the risks associated with using a bottle as a pacifier for an extended period. Rationale: 1. Tooth decay: Prolonged exposure to sugary liquids in the bottle can lead to tooth decay, as the sugar feeds bacteria in the mouth. 2. Ear infections: Bottle-feeding while lying down can increase the risk of ear infections due to fluid entering the Eustachian tube. 3. Education: The response educates the mother on the specific risks associated with prolonged bottle use, promoting informed decision-making. 4. Health promotion: By highlighting the potential negative outcomes, the nurse is advocating for the baby's health and well-being. Incorrect Choices: A: "You're right, bottles make

Correct Answer: D

Rationale: The correct answer is D. At 18 months, it is expected for a child to have erupted around 16 deciduous teeth. The rationale for this answer is based on dental development milestones. By age 3, most children should have their full set of 20 primary teeth. Therefore, the nurse should inform the mother that it is normal for an 18-month-old to have around 16 teeth. Choice A is incorrect as comparing the mother's teeth at that age is irrelevant to the child's dental development. Choice B is incorrect because all 20 deciduous teeth should be present by age 3, not 4. Choice C is incorrect as having 12 teeth at 18 months is below the expected number of erupted teeth for that age.
