Correct Answer: D

Rationale: Before any procedure, it is crucial to ensure that you have the proper authorization and guidelines in place. By checking the physician's order and the patient care plan, you confirm that suctioning is indeed needed and that you follow the specific instructions for that patient. This step helps ensure patient safety and effective care delivery. Once you have verified this information, you can proceed with gathering equipment, performing hand hygiene, and assessing the patient's condition as necessary.

Correct Answer: C

Rationale: Collaborating with interdisciplinary team members to develop a comprehensive care plan demonstrates effective care coordination. In complex healthcare situations, involving various healthcare providers such as physicians, specialists, therapists, social workers, and others is crucial to ensure that all aspects of the patient's care are addressed holistically. By working together, healthcare professionals can share information, expertise, and insights to develop a well-rounded care plan that considers all aspects of the patient's needs. This collaborative approach helps promote better outcomes for the patient and enhances overall care coordination. It also helps to ensure that the patient's preferences and values are taken into account when developing the care plan.

Correct Answer: C

Rationale: Humoral immunity is primarily responsible for protecting against infections by pathogens like viruses. In the case of the hepatitis B virus (HBV), the individual is exposed to the virus and develops immunity, which is typically mediated by antibodies produced by B cells. These antibodies circulate in the blood and can neutralize the virus, preventing future infections. This type of immunity is known as humoral immunity, as it involves the production of antibodies that target specific antigens, such as those present on the surface of the hepatitis B virus. In contrast, passive immunity is when antibodies are transferred from an external source, innate immunity provides immediate, non-specific defenses against pathogens, and cell-mediated immunity involves the activation of T cells to combat intracellular pathogens.

Correct Answer: D

Rationale: The clinical presentation of a patient with chronic kidney disease (CKD) presenting with weakness, anorexia, confusion, severe anemia, low reticulocyte count, elevated serum creatinine, and decreased erythropoietin levels is most consistent with renal failure-associated anemia. In CKD, the kidneys are unable to produce adequate amounts of erythropoietin, a hormone responsible for stimulating red blood cell production in the bone marrow. The decreased erythropoietin levels lead to a state of anemia, characterized by low hemoglobin levels and subsequent symptoms of fatigue and weakness. The anemia in renal failure is typically normocytic and normochromic. Additionally, the elevated serum creatinine in this patient is a hallmark of kidney dysfunction.

Correct Answer: B

Rationale: Acetaminophen (Tylenol) is given pre-operatively to decrease intra-operative anesthetic requirements and post-operative pain. It is a common analgesic that can help reduce the amount of intra-operative anesthesia needed and provide some pain relief during the surgery. Unlike drugs like Celebrex, Ibuprofen, and Demerol, Acetaminophen does not have anti-inflammatory properties, but it is effective in managing pain and can contribute to overall pain control before, during, and after surgery. This makes it a preferred choice for pre-operative medication in order to decrease the need for higher doses of anesthetics and reduce post-operative pain levels.
