When testing visual fields, the nurse is assessing which of the following parts of vision?

Correct Answer: A

Rationale: When testing visual fields, the nurse is assessing the peripheral vision. Peripheral vision refers to the outer area of the visual field, away from the center of gaze. It allows individuals to detect objects, movement, and stimuli in their surroundings without needing to focus directly on them. Testing peripheral vision is important for detecting potential visual field deficits that can impede daily activities and safety, such as driving or navigating crowded spaces. By assessing the peripheral vision, healthcare professionals can identify any limitations or abnormalities that may require further evaluation or intervention.

Correct Answer: D

Rationale: The Dietary Approaches to Stop Hypertension (DASH) diet is recommended by healthcare professionals, including nurses, for clients with hypertension. This diet emphasizes consuming fruits, vegetables, whole grains, lean proteins, and low-fat dairy products while limiting sodium, saturated fats, and cholesterol. These dietary components are known to help lower blood pressure and improve overall health. The DASH diet has been proven effective in numerous studies and is endorsed by organizations like the American Heart Association for managing hypertension. It is important for clients to follow the DASH diet under the guidance of a physician to ensure it is tailored to their individual needs and health status.

Correct Answer: C

Rationale: Orchitis refers to the inflammation of the testicles, which can occur as a complication of mumps infection in males. Mumps is a viral infection caused by the mumps virus, and one of the common complications of mumps in males is orchitis. Orchitis can lead to testicular damage and potentially result in sterility if both testicles are affected. It is essential for males to receive the MMR (measles, mumps, rubella) vaccine to prevent mumps infection and its associated complications, including orchitis and sterility.

Correct Answer: D

Rationale: Surfactant plays a crucial role in the neonate by helping the lungs remain expanded after the initiation of breathing. Surfactant is a substance produced by type II alveolar cells in the lungs that reduces surface tension in the alveoli. By lowering surface tension, surfactant prevents the alveoli from collapsing during expiration, thereby helping the lungs to remain expanded and functional. This function is particularly important in neonates, whose lungs are not yet fully developed and may have difficulty maintaining lung expansion without adequate levels of surfactant. Failure to produce enough surfactant can lead to respiratory distress syndrome in premature infants.

Correct Answer: D

Rationale: Recombinant urate oxidase (rasburicase) effectively lowers uric acid levels in cases of tumor lysis syndrome.
