Why should the nurse closely monitor a client to ensure that the venous access device remains in the vein during a transfusion?

Correct Answer: B

Rationale: In pharmacology, understanding the importance of proper venous access during transfusions is crucial for safe and effective patient care. The correct answer, B) It minimizes the risk of pulmonary embolism, is the most relevant because if the venous access device becomes dislodged during a transfusion, there is a risk that air or clotting material could enter the bloodstream and travel to the lungs, causing a pulmonary embolism, which can be life-threatening. Option A) It minimizes the risk of phlebitis, while important, is not directly related to the immediate danger of a dislodged venous access device during a transfusion. Option C) It minimizes the risk of circulatory overload, and Option D) It minimizes the risk of localized edema, are also important considerations in patient care but are not as directly linked to the specific risk posed by a dislodged venous access device during a transfusion. Educationally, nurses must understand the potential complications associated with venous access devices to provide safe care to patients receiving transfusions. Monitoring the placement and integrity of these devices is essential to prevent adverse events such as pulmonary embolism, highlighting the critical role nurses play in ensuring patient safety during infusion therapy.

Correct Answer: D

Rationale: In the context of pharmacology and anesthesia, the correct answer to the question is D) Procedural sedation. Procedural sedation is a type of anesthesia that provides pain relief, reduces fear and anxiety, and allows patients to undergo unpleasant procedures while maintaining their ability to independently function in terms of cardiorespiratory activity and responsiveness to verbal and tactile stimuli. General anesthesia (option A) involves complete loss of consciousness, including the loss of protective reflexes, while regional anesthesia (option B) targets specific nerves or regions of the body to block sensation in those areas, but may not provide the same level of sedation to manage fear and anxiety during procedures. Epidural anesthesia (option C) specifically refers to the administration of anesthesia into the epidural space, commonly used for pain relief during childbirth or certain surgeries, but it may not provide the same level of conscious sedation as procedural sedation. In an educational context, understanding the different types of anesthesia is crucial for healthcare providers to ensure patient safety and comfort during medical procedures. Procedural sedation allows for a balance between pain relief and maintaining a level of consciousness that enables patients to cooperate with healthcare providers during procedures, making it a valuable tool in various clinical settings.

Correct Answer: D

Rationale: The correct answer is D) It is not available as a pre-exposure vaccine. Botulism antitoxin is used as a treatment for botulism, a rare but serious illness caused by a toxin produced by the bacterium Clostridium botulinum. However, it is important to note that the antitoxin is only used as a post-exposure treatment and is not available as a pre-exposure vaccine. Option A) It causes 9% hypersensitivity is incorrect because hypersensitivity reactions are possible with any medication, but this is not the main drawback specifically related to botulism antitoxin. Option B) It requires monthly booster dosages is incorrect because botulism antitoxin is typically given as a single dose rather than requiring monthly booster doses. Option C) It is not available from the CDC is incorrect because botulism antitoxin is indeed available from the CDC (Centers for Disease Control and Prevention) as part of emergency response supplies. In an educational context, it is crucial for nurses to understand the limitations and appropriate use of medications like botulism antitoxin to ensure safe and effective patient care. Understanding that botulism antitoxin is not available as a pre-exposure vaccine emphasizes the importance of preventive measures such as proper food handling and hygiene practices to avoid exposure to the botulism toxin.

Correct Answer: D

Rationale: In this scenario, the priority diagnosis is option D) Anxiety related to unknown outcomes and perceived threats to body integrity. Anxiety is the most immediate concern as the patient's emotional state is hindering their ability to engage in a necessary discussion about colonoscopy. Addressing the patient's anxiety is crucial to establish effective communication and ensure they understand the importance of diagnostic procedures for their health. Option A is incorrect because while altered bowel patterns are a concern, the patient's emotional state takes precedence. Option B is incorrect as the patient's knowledge deficit is secondary to addressing their anxiety. Option C is incorrect as fluid volume deficit, though important, is not the immediate priority in this situation. Educationally, it is essential to recognize the impact of a patient's emotional state on their willingness to engage in healthcare discussions and procedures. Understanding and addressing patients' anxieties and fears is crucial for effective patient-centered care and promoting positive health outcomes.

Correct Answer: C

Rationale: In this scenario, the most appropriate task to delegate to the nursing assistant is option C, which is to report the amount and type of food consumed from the tray. This task is suitable for delegation as it involves basic observation and documentation skills without requiring specialized knowledge or critical decision-making. Option A, assisting the patient to identify patterns of fatigue, involves a higher level of assessment and understanding of the patient's condition, which should be done by a licensed healthcare provider. Option B, recommending participation in a walking program, involves providing medical advice and guidance, which is beyond the scope of practice for a nursing assistant. Option D, checking the skin for redness and irritation after treatment, involves assessing for potential side effects of radiation therapy, which requires knowledge of skin changes related to radiation and the ability to recognize concerning findings, making it more appropriate for a licensed healthcare provider to perform. Educationally, it is essential for healthcare providers to understand the scope of practice for different members of the healthcare team to ensure safe and effective patient care. Delegation is a crucial skill that requires careful consideration of the task, the person performing it, and the patient's condition to optimize outcomes and promote patient safety.
