health assessment practice questions

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: 1. Anisocoria is a condition where pupils are of unequal size. 2. It is typically caused by issues in the eye muscles or nerves controlling pupil size. 3. The nurse would expect to observe pupils of different sizes. 4. Dilated pupils (choice A) and excessive tearing (choice B) are not indicative of anisocoria. 5. An uneven curvature of the lens (choice D) does not directly relate to pupil size differences. Summary: Correct answer C is supported by the definition of anisocoria and its usual presentation. Choices A, B, and D are incorrect as they do not align with the characteristic feature of anisocoria.

Correct Answer: C

Rationale: Step 1: The described behavior is known as the asymmetric tonic neck reflex (ATNR), a normal infantile reflex. Step 2: The ATNR typically emerges around birth and should disappear between 3 and 4 months of age. Step 3: The reflex helps with hand-eye coordination and development of body awareness. Step 4: Choice A is incorrect as the behavior is not abnormal or related to atonic neck reflex. Step 5: Choice B is incorrect as the reflex typically disappears by 3-4 months, not by the first year of life. Step 6: Choice D is incorrect as it describes a different pattern of movement than what is observed in the ATNR. Summary: The correct answer is C because the behavior described is a normal infantile reflex that typically disappears between 3-4 months of age, aiding in the baby's development.

Correct Answer: A

Rationale: The correct answer is A: "Are you aware of having any allergies?" This question is appropriate because the patient's symptoms of pale, grey, and swollen nasal mucosa suggest an allergic reaction. By asking about allergies, the nurse can gather important information to determine the cause of the symptoms. B: "Do you have an elevated temperature?" - This question is not directly related to the patient's nasal symptoms and does not address the likely allergic reaction. C: "Have you had any symptoms of a cold?" - While cold symptoms may present similarly to allergies, the patient's specific symptoms of pale, grey, and swollen nasal mucosa are more indicative of an allergic reaction. D: "Have you been having frequent nosebleeds?" - This question does not directly address the patient's current symptoms and is not likely related to the nasal mucosa appearance described.

Correct Answer: B

Rationale: The correct answer is B: Dehydration. Depressed and sunken fontanelles in an infant indicate dehydration due to decreased fluid volume. Dehydration causes a decrease in tissue turgor, leading to the fontanelles appearing sunken. Rickets (A) is a condition characterized by weak or soft bones due to vitamin D deficiency. Mental retardation (C) is a developmental disorder, not related to fontanelle appearance. Increased intracranial pressure (D) would cause bulging fontanelles, not depressed fontanelles. Therefore, the most likely condition in this case is dehydration.
