1. A client is being discharged with a new prescription for enoxaparin (Lovenox). Which instruction should the nurse include?
- A. Administer the injection in your thigh.
- B. Do not expel the air bubble from the syringe before injection.
- C. Massage the injection site after administration.
- D. Alternate the injection site between the arms.
Correct answer: B
Rationale: The correct instruction for a client with a prescription for enoxaparin (Lovenox) is not to expel the air bubble from the syringe before injection. This ensures the full dose is delivered without affecting the medication's efficacy. Expelling the air bubble may lead to a loss of medication, resulting in suboptimal treatment. Therefore, it is crucial for the client to follow this instruction to receive the intended therapeutic effect of enoxaparin.
2. A client with severe anemia is being treated with a blood transfusion. Which assessment finding indicates a transfusion reaction?
- A. Elevated blood pressure.
- B. Fever and chills.
- C. Increased urine output.
- D. Bradycardia.
Correct answer: B
Rationale: Fever and chills are classic signs of a transfusion reaction. These symptoms indicate that the body is having a response to the transfused blood, possibly due to incompatibility or an immune reaction. Elevated blood pressure (choice A) is not a typical sign of a transfusion reaction. Increased urine output (choice C) and bradycardia (choice D) are also not characteristic signs of a transfusion reaction. It is crucial to recognize symptoms of a transfusion reaction promptly to prevent further complications and ensure appropriate management.
3. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?
- A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
- B. Absent peristalsis and elevated LES pressure
- C. Absent peristalsis and decreased LES pressure
- D. Vigorous peristalsis and decreased LES pressure
Correct answer: C
Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.
4. An otherwise healthy 45-year-old man presents with severe hematochezia and moderate abdominal cramping since this morning. A barium enema one year ago was normal. On examination, his blood pressure is 120/78 and pulse is 100 while lying; when standing, the blood pressure is 110/76 and pulse is 136. His hematocrit is 34. What is the most likely cause of bleeding?
- A. Diverticular bleed
- B. Duodenal ulcer
- C. Inflammatory bowel disease
- D. Vascular ectasia (watermelon stomach)
Correct answer: B
Rationale: The patient's presentation with hematochezia, moderate abdominal cramping, and hemodynamic changes (increased pulse on standing) suggests an upper gastrointestinal bleed. The drop in blood pressure and rise in pulse rate when standing indicate orthostatic hypotension, which is a sign of significant blood loss. The absence of melena does not rule out an upper GI bleed. Ulcers in the duodenal bulb can erode into the gastroduodenal artery, leading to brisk blood loss. A normal barium enema one year ago makes diverticular bleeding less likely. Inflammatory bowel disease usually does not cause severe acute GI bleeding unless there is ulceration into a vessel. Vascular ectasia, like watermelon stomach, typically presents with chronic blood loss and iron deficiency anemia, more common in older women. The absence of vomiting and the presence of hematochezia make Mallory-Weiss tear less likely in this case.
5. A healthcare professional is participating in the emergency care of a client who has just developed variceal bleeding. What intervention should the healthcare professional anticipate?
- A. Infusion of intravenous heparin
- B. IV administration of albumin
- C. STAT administration of vitamin K by the intramuscular route
- D. IV administration of octreotide
Correct answer: D
Rationale: The correct intervention for variceal bleeding is IV administration of octreotide. Octreotide helps control bleeding from varices by reducing portal blood flow and pressure, which is crucial in managing this emergency situation.
