A nurse discovers scabies when assessing a client who has just been transferred to the medical-surgical unit from the day surgery unit.
To prevent scabies infection in other clients, the nurse should:

Wash hands, apply a pediculicide to the client's scalp, and remove any observable mites.

Place the client on enteric precautions.

Isolate the client's bed linens until the client is no longer infectious.

Notify the nurse in the day surgery unit of a potential scabies outbreak.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Pediculicides are used to treat lice, not scabies. Proper hand hygiene is important, but applying pediculicide is not necessary for scabies management.

Choice B rationale

Enteric precautions are for infections transmitted via the fecal-oral route, not for scabies, which requires contact precautions.

Choice C rationale

Isolating the client's bed linens and applying contact precautions help prevent the spread of scabies to other clients.

Choice D rationale

Notifying the day surgery unit of a potential scabies outbreak is important, but it does not directly prevent infection in other clients.

Correct Answer is D

Explanation

Choice A rationale

Necrosis is tissue death resulting from prolonged pressure, often a consequence rather than the direct cause of pressure ulcers. The primary cause is sustained pressure impairing blood flow.

Choice B rationale

Low capillary pressure does not directly cause pressure ulcers. They result from sustained external pressure exceeding capillary perfusion pressure, leading to ischemia and tissue damage.

Choice C rationale

Increased mobility actually prevents pressure ulcers by reducing sustained pressure on any one area, enhancing blood flow and tissue health. Immobility is a significant risk factor, not increased mobility.

Choice D rationale

Extrinsic factors like sustained pressure, friction, shear, and moisture contribute directly to pressure ulcer development by compromising skin integrity and blood flow, leading to tissue ischemia and damage.

A. Frontal lobe. B. Occipital lobe. C. Parietal lobe. D. Temporal lobe.

Correct Answer is A

Explanation

Choice A rationale

The frontal lobe is responsible for various high-level cognitive functions, including the regulation of emotions and affect. It plays a crucial role in personality expression, decision-making, and moderating social behavior. Damage or dysfunction in the frontal lobe can lead to changes in personality and affect, including a flat affect.

Choice B rationale

The occipital lobe is primarily responsible for processing visual information. It is located at the back of the brain and is not involved in regulating emotions or affect. Therefore, it does not play a role in the client’s flat affect.

Choice C rationale

The parietal lobe is involved in processing sensory information such as touch, temperature, and pain. It also plays a role in spatial orientation and motor control. However, it is not directly involved in regulating emotions or affect. Thus, it does not contribute to the client’s flat affect.

Choice D rationale

The temporal lobe is involved in processing auditory information and is critical for memory and language comprehension. While it plays a role in emotion processing, it is not the primary lobe responsible for affect. The frontal lobe has a more direct impact on emotional regulation and affect.
