Adult Health Nursing Test Banks

Correct Answer: A

Rationale: The nurse should prioritize ensuring proper zeroing and calibration of the ICP monitoring system to ensure procedural accuracy and reliability of the measurements obtained. Proper zeroing involves setting the transducer at the level of the patient's external auditory meatus (ear), which serves as a reference point for accurate ICP readings. Calibration is necessary to establish accurate pressure measurements. Incorrect zeroing or calibration can lead to inaccurate ICP readings, which can impact clinical decision-making for patients with traumatic brain injury. Positioning the patient in a high-Fowler's position, administering prophylactic antibiotics, or placing the ICP monitor in the subarachnoid space via lumbar puncture are not directly related to ensuring the accuracy of the ICP monitoring procedure.

Correct Answer: D

Rationale: When someone is bitten by a dog, the most important first aid step is to wash the wound thoroughly with running water. This helps to remove any dirt or bacteria from the wound, reducing the risk of infection. Washing the wound with garlic (choice A) is not recommended as it can irritate the skin and may not effectively clean the wound. Feeding the dog (choice B) is not relevant to treating the bite wound. Bleeding the bitten area (choice C) is also not necessary and can actually increase the risk of infection. Therefore, the best advice the nurse should give in case of a dog bite is to wash the wound thoroughly with running water.

Correct Answer: B

Rationale: Ramona Mercer's becoming a mother (BAM) theory emphasizes the dynamic transformation and evolution of a woman's persona as she transitions into motherhood. This theory acknowledges that becoming a mother is a process involving significant changes in a woman's identity, roles, and relationships. It goes beyond just the physical aspects of giving birth and delves into the psychological, emotional, and social aspects of motherhood. Therefore, statement B aligns with the core principles of Mercer's BAM theory and fosters the understanding of the process of becoming a mother.

Correct Answer: C

Rationale: The presence of persistent, severe perineal pain along with ecchymosis and swelling of the perineum can indicate a complication such as a hematoma. A hematoma is a collection of blood that can occur in the perineal area postpartum, usually as a result of trauma during delivery. It is essential to notify the healthcare provider immediately to assess the situation, provide appropriate treatment, and prevent further complications. Applying ice packs or administering additional analgesic medication may not address the underlying issue of a possible hematoma, so prompt medical evaluation is crucial in this situation.

Correct Answer: A

Rationale: Toll-like receptors (TLRs) are a group of cellular receptors responsible for recognizing pathogen-associated molecular patterns (PAMPs), which are molecular components commonly found on pathogens like bacteria and viruses. When TLRs recognize these PAMPs, they initiate signaling pathways that trigger the innate immune response, leading to inflammation, antimicrobial defense, and the activation of adaptive immunity. B cell receptors (BCRs) and T cell receptors (TCRs) are involved in adaptive immune responses and recognize specific antigens rather than PAMPs. Fc receptors primarily bind to the Fc portion of antibodies and are involved in antibody-mediated immune responses. Thus, TLRs specifically play a critical role in sensing and responding to pathogens through the recognition of PAMPs.
