1. Which type of Leukocyte is involved with allergic responses and the destruction of parasitic worms?

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.

2. The nurse working on a mental health unit is prioritizing nursing care activities due to a staffing shortage. One practical nurse (PN) is on the unit with the nurse, and another RN is expected to arrive within two hours. Clients need to be awakened, and morning medications need to be prepared. Which plan is best for the nurse to implement?

Correct answer: C

Rationale: The best plan for the nurse to implement is to ask the PN to administer medications as clients are awakened. This approach ensures that medication administration and client care are efficiently managed despite the staffing shortage. Option A is incorrect as it may disrupt the workflow and create unnecessary chaos. Option B is not the best choice as it does not address the immediate need for medication administration. Option D is not ideal as it delays client care until additional staff arrive, potentially compromising patient safety and timely medication administration.

3. When planning to contact the healthcare provider about a client's need for a belt restraint, what information is most important to report?

Correct answer: B

Rationale: The correct answer is B. When reporting to the healthcare provider about a client's need for a belt restraint, it is crucial to provide information on the measures already taken to maintain client safety. This includes detailing alternative strategies that have been tried before considering restraint use. This information helps the healthcare provider assess the situation comprehensively and explore other safety interventions. Choices A, C, and D, though relevant to the client's care, are not as critical to report when discussing the need for a belt restraint. Pressure ulcers (Choice A) are important but not directly related to the need for a belt restraint. The presence of special mattresses (Choice C) may influence overall care but is not the most pertinent information when considering restraints. Current vital signs and oxygen saturation (Choice D) are essential for the client's overall assessment but do not directly address the need for a belt restraint.

4. A female client with breast cancer who completed her first chemotherapy treatment today at an outpatient center is preparing for discharge. Which behavior indicates that the client understands her care needs?

Correct answer: D

Rationale: The correct answer is D because reporting any new or worsening symptoms to the nurse is crucial for the early detection of potential complications. This behavior shows that the client understands the importance of monitoring her health status post-chemotherapy treatment. Choices A, B, and C are incorrect because while renting movies, borrowing books, discussing dietary restrictions, and arranging follow-up appointments are all important aspects of care, the most critical factor immediately after chemotherapy is to monitor and report any new or worsening symptoms to healthcare providers.

5. Which techniques should be used to administer an intradermal (ID) injection for a Mantoux test to screen for tuberculosis (TB)? Select all that apply.

Correct answer: A

Rationale: Observing for an intradermal bleed after the antigen is injected is a proper technique for an ID injection. This is important to confirm the correct placement of the injection. Choice B is correct because the recommended site for an ID injection for a Mantoux test is the volar surface of the forearm. Choice C is incorrect because the standard needle size for an ID injection is usually 26 or 27 gauge with a length of 1/4 to 5/8 inches, not 25 gauge with a length of 1/2 inch. Choice D is incorrect because the needle should be inserted into the skin with the bevel facing up, not down.
