Correct Answer: B

Rationale: When a nurse observes rapid, involuntary oscillating movements of the eyeball in a client, this is described as nystagmus. Nystagmus appears as a fine oscillating movement, most notable around the iris. It is important to assess for nystagmus when evaluating ocular muscle weakness. Mild nystagmus at extreme lateral gaze is considered normal; nystagmus in any other position is not. Ptosis refers to a drooping of the eyelid, not rapid eye movements. Scleral icterus is the yellowing of the sclera up to the cornea, indicating jaundice, not related to eye movements. Exophthalmos is a noticeable protrusion of the eyeball, typically seen in hyperthyroidism, not associated with rapid oscillating eye movements.

Correct Answer: A

Rationale: The correct answer is the left lateral position. Placing the laboring client in the left lateral position is beneficial because it promotes blood flow to the placenta. Late decelerations indicate potential issues with fetal oxygenation, and changing the position to left lateral can help improve placental perfusion. Choices B, C, and D are incorrect because lithotomy, semi-Fowler's, and right lateral positions do not specifically address the need for improved blood flow to the placenta in cases of late decelerations.

Correct Answer: D

Rationale: Factors correlated with poverty often include a high infant mortality rate, frequent use of Emergency Departments, and consultation with folk healers, as these indicate limited access to healthcare. Dental problems are prevalent in poverty due to a lack of preventive care and access to treatments. High infant mortality is a significant issue linked with poverty as it reflects poor healthcare access. Families in poverty might resort to Emergency Departments for healthcare due to financial barriers. Consulting folk healers is common in communities with limited access to formal healthcare. However, a low incidence of dental problems is less likely in impoverished families due to the lack of preventive services and the presence of other health issues.

Correct Answer: B

Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.

Correct Answer: D

Rationale: Adventitious breath sounds are abnormal sounds that are not normally heard in the lungs. These sounds are added sounds superimposed on the breath sounds. They are caused by air colliding with secretions in the tracheobronchial passageways or when previously deflated airways pop open. Hollow sounds heard over the trachea and larynx are normal bronchial (tracheal) breath sounds, not adventitious. Rustling sounds heard over the peripheral lung fields are normal vesicular breath sounds, not adventitious. Therefore, the correct answer is that adventitious breath sounds are abnormal sounds that should not be heard in the lungs.
