health assessment practice questions

Correct Answer: B

Rationale: The correct answer is B: the lump is mobile and not hard. A cancerous thyroid nodule is typically fixed and hard, whereas a noncancerous nodule is more likely to be mobile and soft. This characteristic suggests it may be a benign condition such as a thyroid cyst rather than a malignant tumor. The other choices are incorrect because A: tenderness does not necessarily indicate benignity or malignancy, C: disappearance when smiling is more related to a salivary gland issue, and D: hardness and fixation are more indicative of a potentially cancerous nodule.

Correct Answer: D

Rationale: The correct answer is D because asking the patient to hold his nose and swallow causes the eustachian tube to open, equalizing pressure in the middle ear. This action will cause the eardrum to bulge slightly outward, making landmarks more visible. Choice A is incorrect as age alone does not preclude the use of this technique. Choice B is incorrect because this technique is not primarily used for assessing otitis media. Choice C is incorrect as it is not specific to upper respiratory infections.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. Enlargement of the thyroid gland during pregnancy is a normal finding due to hormonal changes. 2. The thyroid gland enlarges to meet the increased demands of thyroid hormone production. 3. This condition is known as gestational thyrotoxicosis and is usually benign. 4. No further testing is needed for thyroid cancer unless other concerning symptoms are present. Summary: A: Not relevant as iodine deficiency is not typically associated with thyroid enlargement in pregnancy. B: Incorrect as early signs of goitre would involve more pronounced symptoms than just slight enlargement. D: Unnecessary as thyroid cancer is not a common concern in this scenario of a slightly enlarged thyroid in the third trimester of pregnancy.

Correct Answer: B

Rationale: The correct answer is B: impetigo. The characteristics of moist, thin-roofed vesicles with a thin erythematous base are classic features of impetigo, a bacterial skin infection commonly seen in children. Impetigo is highly contagious and commonly affects the face and buttocks. The presence of blisters and scabs further supports the diagnosis of impetigo. Explanation of other choices: A: Eczema typically presents as dry, itchy patches of skin with redness and scaling. It does not usually manifest as vesicles or blisters. C: Herpes zoster, also known as shingles, presents as a painful rash with grouped vesicles on one side of the body along a nerve pathway. It is uncommon in children and usually affects older individuals. D: Diaper dermatitis is a common rash in infants due to prolonged skin exposure to urine and feces. It typically presents as redness, irritation, and possibly skin breakdown in the diaper

Correct Answer: A

Rationale: The correct answer is A because at 7 months, infants typically have developed the ability to localize sounds. When clapping hands, the expected response is for the infant to turn their head towards the sound source, indicating their ability to detect and localize the sound. This behavior reflects the normal auditory development at this age. Choice B is incorrect because by 7 months, infants should show some response to noise, such as turning their head or showing some interest. Choice C is incorrect as the startle and acoustic blink reflex typically occur in response to sudden loud noises, but at 7 months, the infant should also be able to localize the source of the sound. Choice D is incorrect as stopping all movement and appearing to listen is not a typical response expected from a 7-month-old when hearing a sound. Infants at this age are more likely to actively turn towards the sound source to investigate.
