1. What is the primary purpose of administering IV fluids to a patient in septic shock?
- A. To reduce blood pressure.
- B. To increase cardiac output.
- C. To stabilize blood glucose levels.
- D. To maintain adequate tissue perfusion.
Correct answer: D
Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.
2. A 57-year-old male client is scheduled to have a stress-thallium test the following morning and is NPO after midnight. At 0130, he is agitated because he cannot eat and is demanding food. Which response is best for the nurse to provide to this client?
- A. I'm sorry sir, you have a prescription for nothing by mouth from midnight tonight.
- B. I will let you have one cracker, but that is all you can have for the rest of tonight.
- C. What did the healthcare provider tell you about the test you are having tomorrow?
- D. The test you are having tomorrow requires that you have nothing by mouth tonight.
Correct answer: D
Rationale: Being direct and explaining to the client that the test requires him to be NPO, is the most therapeutic statement because the nurse is responding to the client's question and providing him the reason why.
3. The nurse is preparing to administer intravenous gentamicin to an infant through an intermittent needle. The nurse notes that the infant has not had a wet diaper for several hours. The nurse will perform which action?
- A. Administer the medication and give the infant extra oral fluids.
- B. Contact the provider to request adding intravenous fluids when giving the medication.
- C. Give the medication and obtain a serum peak drug level 45 minutes after the dose.
- D. Hold the dose and contact the provider to request a serum trough drug level.
Correct answer: D
Rationale: In this scenario, the infant not having a wet diaper for several hours indicates a potential decrease in urine output, which can be a sign of nephrotoxicity related to gentamicin. The correct action for the nurse is to hold the dose and contact the provider to request a serum trough drug level. This is important to monitor the drug levels and ensure that they are not reaching toxic levels. Administering the medication without addressing the decreased urine output could potentially lead to further nephrotoxicity. Contacting the provider to add intravenous fluids or obtaining a serum peak drug level are not the most appropriate actions in this situation as the priority is to assess for potential nephrotoxicity and ensure patient safety.
4. A client who is anxious about an impending surgery is at risk for respiratory alkalosis. For which signs and symptoms of respiratory alkalosis does the nurse assess this client?
- A. Disorientation and dyspnea
- B. Drowsiness, headache, and tachypnea
- C. Tachypnea, dizziness, and paresthesias
- D. Dysrhythmias and decreased respiratory rate and depth
Correct answer: C
Rationale: The correct answer is C: Tachypnea, dizziness, and paresthesias. When a client is anxious, they may hyperventilate, leading to respiratory alkalosis. Tachypnea (rapid breathing) is a common sign of respiratory alkalosis. Dizziness and paresthesias (tingling or numbness in the extremities) are also typical symptoms. Choices A, B, and D are incorrect. Disorientation and dyspnea (Choice A) are not specific signs of respiratory alkalosis. Drowsiness, headache, and tachypnea (Choice B) may be more indicative of other conditions. Dysrhythmias and decreased respiratory rate and depth (Choice D) are not consistent with the expected signs of respiratory alkalosis.
5. A 58-year-old client who has been post-menopausal for five years is concerned about the risk for osteoporosis because her mother has the condition. Which information should the nurse offer?
- A. Osteoporosis is a progressive genetic disease with no effective treatment.
- B. Calcium loss from bones can be slowed by increasing calcium intake and exercise.
- C. Estrogen replacement therapy should be started to prevent the progression of osteoporosis.
- D. Low-dose corticosteroid treatment effectively halts the course of osteoporosis.
Correct answer: B
Rationale: Post-menopausal females are at risk for osteoporosis due to the cessation of estrogen secretion. While genetics can play a role, osteoporosis is not solely a genetic disease. Increasing calcium intake, along with vitamin D supplementation and weight-bearing exercise, can help prevent further bone loss by slowing down calcium loss from bones. Estrogen replacement therapy is no longer recommended as a first-line treatment for osteoporosis due to associated risks. Corticosteroid treatment is not typically used as a primary treatment for osteoporosis.
