Which serotonin antagonist can be used to relieve nausea and vomiting?

Correct Answer: B

Rationale: The correct answer is B: ondansetron (Zofran). Ondansetron is a selective serotonin receptor antagonist that effectively targets the serotonin receptors in the chemoreceptor trigger zone to relieve nausea and vomiting. It is commonly used in chemotherapy-induced nausea and vomiting. A: Metoclopramide is a dopamine receptor antagonist and primarily used for gastrointestinal motility disorders, not specifically for nausea relief. C: Hydroxyzine is an antihistamine with sedative properties, primarily used for anxiety and itching, not specifically for nausea relief. D: Prochlorperazine is a dopamine receptor antagonist primarily used for treating psychotic disorders, not specifically for nausea relief. In summary, ondansetron is the correct choice as it targets serotonin receptors specifically for relieving nausea and vomiting, whereas the other options focus on different mechanisms of action.

Correct Answer: A

Rationale: The correct answer is A: "Smoking increases the risk of complications during surgery." Smoking constricts blood vessels, reduces oxygen levels, and impairs the body's ability to heal. This can lead to increased risks of infections, delayed wound healing, and other complications during and after surgery. Choice B is vague and does not address the specific risks associated with smoking. Choice C is too general and does not emphasize the immediate risks related to surgery. Choice D implies a benefit after surgery rather than focusing on the risks associated with smoking before surgery.

Correct Answer: C

Rationale: The correct answer is C: Chocolate. Chocolate is known to trigger heartburn in individuals with GERD due to its high fat content and caffeine. Fat relaxes the lower esophageal sphincter, allowing stomach acid to flow back up the esophagus, leading to heartburn. Caffeine can also relax the sphincter and trigger acid reflux. Lettuce (A) and eggs (B) are generally well-tolerated and do not commonly trigger heartburn. Butterscotch (D) may be high in fat and sugar, but it is less likely to cause heartburn compared to chocolate.

Correct Answer: C

Rationale: The correct answer is C: Monitor blood pressure. When a client presents with acute abdominal pain, monitoring blood pressure is crucial as it can help assess for potential complications like hypovolemic shock or internal bleeding. Changes in blood pressure may indicate worsening condition and prompt the need for immediate intervention. Monitoring vital signs (A) is important but blood pressure takes precedence in this scenario. Assessing abdominal tenderness (B) is valuable but does not directly address potential life-threatening issues. Monitoring for dehydration (D) is also important but not the most immediate concern in the case of acute abdominal pain.

Correct Answer: A

Rationale: The correct answer is A: Inspecting feet daily for signs of injury. This is crucial for patients with diabetes and peripheral neuropathy to prevent complications like infections and ulcers. By inspecting their feet daily, the patient can identify any injuries or abnormalities early and seek prompt medical attention. This proactive approach can help prevent serious consequences such as amputations. Summary of incorrect choices: B: Taking medications only when experiencing symptoms - This is not recommended as medications for diabetes and neuropathy are often prescribed to prevent complications and manage the conditions on a daily basis. C: Exercising to increase foot circulation - While exercise is beneficial, patients with peripheral neuropathy may have decreased sensation in their feet, increasing the risk of injury during exercise. D: Wearing tight-fitting shoes to avoid blisters - Tight-fitting shoes can cause pressure points and increase the risk of foot injuries, especially in patients with neuropathy.

Correct Answer: A

Rationale: The correct answer is A: A trained interpreter. Choosing a trained interpreter ensures accurate communication and confidentiality. Professional interpreters have the necessary language skills and cultural competence to facilitate effective communication between the healthcare provider and the patient. Using a family member (choices B and C) may compromise confidentiality and accuracy due to potential bias or lack of professional training. Similarly, selecting a volunteer university student (choice D) may result in misinterpretation or breach of privacy as they may not have the same level of expertise as a trained interpreter. Ultimately, the most appropriate choice is a trained interpreter to ensure clear and accurate communication while respecting the patient's privacy and dignity.

Correct Answer: A

Rationale: The correct answer is A: Apply a sterile dressing. Firstly, cover the wound with a sterile occlusive dressing to prevent air from entering the pleural space, reducing the risk of tension pneumothorax. This also helps to prevent infection and further complications. Administering morphine (B) or nitroglycerin (D) is not the priority in this situation as managing the chest wound is crucial. Applying an airtight dressing (C) may lead to tension pneumothorax if not done properly. Therefore, the immediate action should be to apply a sterile dressing to stabilize the wound and prevent further complications.

Correct Answer: A

Rationale: The correct answer is A: Chronic kidney disease (CKD). Patients with diabetes and hypertension are at increased risk for developing CKD due to the damaging effects of high blood sugar and elevated blood pressure on the kidneys. The nurse should monitor for signs and symptoms of kidney dysfunction such as proteinuria, elevated creatinine levels, and decreased glomerular filtration rate. B: Chronic pain is not directly related to the patient's history of diabetes and hypertension. While the patient may experience pain as a result of complications from these conditions, it is not the primary complication to monitor for in this case. C: Hypotension, or low blood pressure, is not a common complication associated with diabetes and hypertension. These conditions typically lead to high blood pressure rather than low blood pressure. D: Sepsis is a serious infection that can occur in any patient, but it is not a direct complication specifically related to diabetes and hypertension. Monitoring for sepsis would be important in a broader context but is not

Correct Answer: C

Rationale: The correct answer is C: Mental. Nursing assessments typically include physical, focused, and emergency assessments. Mental assessments are more commonly associated with psychiatric nursing rather than general nursing assessments. Mental assessments focus on assessing a patient's mental status, emotions, and cognitive functions, which are not typically part of routine nursing assessments. Therefore, mental assessments do not fall under the types of assessments typically performed by general nurses.
