health assessment practice questions nursing

Correct Answer: C

Rationale: The correct answer is C because purpura is characterized by the presence of confluent and extensive patches of petechiae and ecchymoses. Petechiae are small, pinpoint hemorrhages less than 2mm in size, and ecchymoses are larger bruises. This presentation is indicative of a more severe underlying condition, such as a bleeding disorder or vasculitis. Choice A is incorrect as it describes spider veins or telangiectasias, not purpura. Choice B describes a birthmark, not purpura. Choice D is incorrect as it describes petechiae, not purpura, which involves larger areas of bleeding.

Correct Answer: A

Rationale: The correct answer is A: acquired immunodeficiency syndrome (AIDS). The dark red confluent macule on the hard palate is known as Kaposi's sarcoma, a common manifestation of AIDS. This lesion is caused by Human Herpesvirus 8 and is often seen in patients with compromised immune systems. Measles (B) typically presents with a rash, not a dark red macule. Leukemia (C) does not typically manifest as a dark red macule in the mouth. Carcinoma (D) refers to cancer and would present differently than Kaposi's sarcoma. In summary, the presence of a dark red confluent macule on the hard palate in a patient with a history of intravenous drug abuse is highly suggestive of AIDS, specifically Kaposi's sarcoma.

Correct Answer: A

Rationale: The correct answer is A: At birth, the head is one fifth the total length. This is because newborns have relatively larger heads compared to their body size. This is known as cephalocaudal growth, where development starts from the head and progresses down the body. The head being one-fifth of the total length is a normal proportion in newborns. Choice B is incorrect because at birth, the chest circumference is usually greater than the head circumference. Choice C is incorrect as the head size reaches about 80% of its final size by age 2, not 3 years old. Choice D is incorrect because the closure of the anterior fontanelle at 2 months does not necessarily mean the head will appear proportionate to the body; it continues to grow in proportion to the body size.

Correct Answer: B

Rationale: The correct answer is B: know that these are scars caused from frequent ear infections. The presence of dense white patches on the tympanic membrane in a patient with a history of chronic ear infections indicates scarring from previous infections. This is a common finding in individuals who have experienced recurrent middle ear infections. The other choices are incorrect because: A) Fungal infections typically present with different characteristics such as discoloration or debris in the ear canal, not dense white patches on the tympanic membrane. C) Blood in the middle ear would manifest as redness or hemorrhage, not white patches. D) While scarring may affect hearing, the description of the tympanic membrane in this case does not suggest any immediate concern for hearing loss.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. Immediate intervention is crucial as the newborn needs clear airways for breathing. 2. Inability to suction the nares can lead to respiratory distress and compromise the infant's oxygenation. 3. Waiting or attempting again may delay necessary actions, risking the baby's health. 4. Physician's assistance may be needed, but recognizing the urgency is the nurse's responsibility to ensure timely care. Summary of Incorrect Choices: A. Attempting to suction again with a bulb syringe may not resolve the issue and delay necessary intervention. B. Waiting for the infant to stop crying is not ideal as it may prolong the risk of respiratory distress. D. While physician assistance may be necessary, immediate recognition of the critical situation is the nurse's primary responsibility.
