CAT Exam Practice Test

Correct Answer: D

Rationale: Placing ID bands on the infant and mother is crucial to ensure correct identification and prevent mix-ups. This step is essential for maintaining proper identification of the newborn and the mother, facilitating safe care delivery. Before leaving the delivery room, ensuring proper identification is a priority to prevent any errors. Obtaining the infant's vital signs may be important but does not take precedence over ensuring correct identification. Observing the infant latching onto the breast is crucial for breastfeeding initiation but can be done after proper identification. Administering a vitamin K injection is also important but should not delay the immediate identification process.

Correct Answer: A

Rationale: The correct answer is A: Topical corticosteroid. Topical corticosteroids are commonly used to manage itching in eczema by reducing inflammation and suppressing the immune response. In this case, for severe pruritus in eczema, a topical corticosteroid would be appropriate. Choice B, Topical scabicide, is used to treat scabies, not eczema. Choice C, Topical alcohol rub, is not typically used to manage pruritus in eczema. Choice D, Transdermal analgesic, is more for pain relief and not specifically targeted at managing itching associated with eczema.

Correct Answer: A

Rationale: In this situation, the most important action for the nurse to take is to explain the importance of regular dressing changes to the client. By doing so, the nurse can help the client understand the necessity for wound healing and infection prevention. Administering anti-anxiety medication (Choice B) may not address the root cause of the client's anxiety, which is the lack of understanding. Proceeding with the scheduled dressing change (Choice C) without addressing the client's concerns can worsen their anxiety and decrease trust. Encouraging the client to express any anxieties (Choice D) is important but not as crucial as ensuring the client comprehends the rationale behind the dressing change.

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: 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.
