1. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?
- A. platelet count
- B. prothrombin time (PT)
- C. partial thromboplastin time (PTT)
- D. D-dimer
Correct answer: D
Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.
2. What is the best position for a client immediately following a bilateral salpingooophorectomy?
- A. Fowler's
- B. Modified Sims
- C. Side lying
- D. Flat supine
Correct answer: C
Rationale: The best position for a client immediately following a bilateral salpingooophorectomy is side lying. This position promotes comfort with the knees flexed and ensures proper airway management. Fowler's position (Choice A) would not be ideal as it involves sitting at a 90-degree angle, potentially causing discomfort after this procedure. Modified Sims position (Choice B) is typically used for rectal examinations, not for post-surgical management. Flat supine (Choice D) may not be the best choice immediately after surgery as it does not provide the same level of comfort and airway protection as side lying with knees flexed.
3. A nurse is instructing a patient about the warning signs of Digitalis side effects. Which of the following side effects should the nurse tell the patient are sometimes associated with excessive levels of Digitalis?
- A. Seizures
- B. Muscle weakness
- C. Depression
- D. Anxiety
Correct answer: B
Rationale: The correct answer is 'Muscle weakness.' Palpitations and muscle weakness are commonly associated with excessive levels of Digitalis. Seizures, depression, and anxiety are not typically linked to Digitalis toxicity. Seizures could be more related to other medications or conditions, while depression and anxiety are not commonly reported side effects of Digitalis.
4. The client is admitted to the hospital following a motor vehicle accident and has sustained a closed chest wound. Which assessment finding is consistent with a flail chest?
- A. Biot's respirations
- B. Sucking sounds during respirations
- C. Paradoxical chest wall movement
- D. Hypotension and bradycardia
Correct answer: C
Rationale: The correct assessment finding consistent with a flail chest is paradoxical chest wall movement. This occurs when a segment of the chest wall moves in the opposite direction to the rest of the chest during respiration. Biot's respirations (Choice A) are a pattern of breathing characterized by groups of quick, shallow inspirations followed by regular or irregular periods of apnea. Sucking sounds during respirations (Choice B) may indicate air entering or leaving the chest cavity through a wound. Hypotension and bradycardia (Choice D) may be present due to other factors such as shock, but they are not specific to a flail chest.
5. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
- A. metoclopramide (Reglan)
- B. ondansetron (Zofran)
- C. hydroxyzine (Vistaril)
- D. prochlorperazine (Compazine)
Correct answer: B
Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.
