Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

Correct Answer: C

Rationale: The correct answer is C because in cases of suspected spinal injury, it is crucial to keep the spine immobilized to prevent further damage. Rolling Mr. Gabatan onto his abdomen helps protect his spine by maintaining alignment. Placing a pad under his head provides support and covering him with any material available helps maintain his body temperature. Moving him without proper spinal precautions (options A, B, D) could worsen his condition. Seeking additional help is important, but ensuring spinal immobilization comes first. Sitting him up or moving him onto a flat piece of lumber can exacerbate spinal injuries. Therefore, option C is the most appropriate initial action.

Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.

Correct Answer: B

Rationale: Step-by-step rationale: 1. CD4+ cells are a type of white blood cell crucial for immune function. 2. HIV targets and destroys CD4+ cells, leading to immune system damage. 3. Measuring CD4+ levels helps determine the extent of this damage. 4. Therefore, the correct answer is B. Summary: A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose. C: Level of the viral load - Measured separately from CD4+ levels. D: Resistance to antigens - CD4+ levels do not directly indicate resistance.

Correct Answer: D

Rationale: The correct answer is D because a brain abscess can be caused by direct invasion of the brain, spread of infection by other organs, and spread of infection from nearby sites. Direct invasion can occur from trauma or surgery, while infections from other organs like the lungs or heart can travel through the bloodstream to the brain. Infections from nearby sites such as the sinuses or ears can also spread to the brain. Therefore, all of these mechanisms can lead to the formation of a brain abscess. Choices A, B, and C alone do not encompass all the possible causes of a brain abscess, making D the correct comprehensive answer.

Correct Answer: B

Rationale: The correct answer is B because maintaining the head of the bed at a 30-degree angle can cause the radioactive material to shift within the client's body, increasing the risk of radiation exposure. This position should be avoided to prevent displacement of the applicator. A: Strict bed rest is appropriate to minimize movement and dislodgement of the applicator, ensuring proper treatment delivery. C: Providing a bed bath does not pose a radiation hazard as long as proper precautions are taken. D: Checking the applicator's position every 4 hours is essential for monitoring and ensuring it remains in place to deliver the intended treatment.
