Correct Answer: A

Rationale: In emergency situations where AB negative blood is unavailable, type A negative blood can be transfused to a patient with AB negative blood type. Type A negative blood is compatible with AB negative blood, making it a suitable option until the correct blood type becomes available. Transfusion of Type A negative blood is crucial to address the severe anemia promptly. Rechecking the client's hemoglobin, blood type, and Rh factor (Choice B) may delay necessary treatment. Administering normal saline solution (Choice C) is not a substitute for blood transfusion in cases of severe anemia. Obtaining additional consent for the administration of type A negative blood (Choice D) is unnecessary as the situation is emergent and the blood type is compatible.

Correct Answer: D

Rationale: The correct answer is D because viral meningitis with a slight increase in temperature is less acute and complex compared to the other conditions. This change in temperature does not indicate a critical or urgent situation requiring immediate attention or intervention beyond the scope of a practical nurse. Choices A, B, and C present more significant changes in health status such as a decrease in Glasgow Coma Scale score, an increase in intracranial pressure indicated by blood pressure changes, and a significant drop in blood pressure, respectively. These changes require closer monitoring and intervention by registered nurses due to the higher acuity and complexity of care needed for these conditions.

Correct Answer: A

Rationale: Assisting the client in identifying goals for the day is the most important aspect of the plan of care for a client with severe depression. Setting achievable daily goals helps engage the client in activities and promotes a sense of accomplishment, which can contribute to gradual improvement in their condition. Encouraging participation in team sports may be overwhelming for a client with severe depression as it requires a significant level of energy and motivation that the client may not possess at this time. Group sessions focusing on self-esteem and daily affirmations are beneficial interventions, but they may not have an immediate impact compared to setting achievable daily goals that can provide a sense of purpose and achievement for the client.

Correct Answer: A

Rationale: The correct answer is A. Bedfast clients with increased serum BUN and creatinine levels are at high risk for overflow incontinence. This occurs due to decreased bladder function and reduced ability to sense bladder fullness, leading to the bladder overfilling and leaking urine. Choice B describes symptoms related to possible urinary tract infections or renal issues, but these do not directly indicate overflow incontinence. Choice C, a history of frequent urinary tract infections, may suggest other urinary issues but not specifically overflow incontinence. Choice D, a confused client who forgets to go to the bathroom, is more indicative of functional incontinence rather than overflow incontinence.

Correct Answer: C

Rationale: Eosinophils are the correct answer. Eosinophils are specialized white blood cells that play a crucial role in allergic responses and combating parasitic infections. They release substances to destroy parasites and modulate allergic reactions. Neutrophils (Choice A) are mainly involved in fighting bacterial infections. Lymphocytes (Choice B) play a key role in the immune response, including antibody production, but are not primarily responsible for combating parasites or allergic responses. Monocytes (Choice D) are involved in immune defense, differentiating into macrophages or dendritic cells, but they are not mainly associated with allergic responses or parasitic worm destruction.
