1. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?
- A. Depressed function of the CNS
- B. Increased blood flow
- C. Decreased venous capacity
- D. Pain relief
Correct answer: C
Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.
2. Why is starting a low CHO diet a contraindication for a client with renal insufficiency?
- A. As long as the client eats a minimum of 30g of CHO/day, there should be no problem.
- B. The client's clinical condition is a contraindication to starting a low CHO diet.
- C. Calcium supplements should be utilized to prevent the development of osteoporosis while on a low CHO diet.
- D. As long as the client eats foods that are high biologic protein sources, a low CHO diet can be followed.
Correct answer: B
Rationale: A client with renal insufficiency should not start a low CHO diet because it could result in an increased renal solute load. Clients with renal or liver disease require protein control in their diet to prevent complications. Proteins used must be of high biologic value, and protein intake is usually weight-based. Protein levels may be adjusted based on the client's clinical condition. A minimum level of carbohydrates is needed in the diet to spare protein. Vitamin and mineral supplements might be needed for clients with liver failure. The dietician plays a crucial role in calculating specific nutrient requirements for these clients and monitoring outcomes in conjunction with the healthcare team. Choice A is incorrect because simply consuming a minimum amount of carbohydrates does not address the issue of increased renal solute load. Choice C is incorrect as calcium supplements are not the primary concern when considering a low CHO diet for a client with renal insufficiency. Choice D is incorrect as the focus should be on the contraindication of a low CHO diet for a client with renal insufficiency rather than just high biologic protein sources.
3. After experiencing a left frontal lobe CVA, a fifty-five-year-old man is being monitored by a nurse. The patient's family is not present in the room. What should the nurse observe most closely for?
- A. Changes in emotion and behavior
- B. Monitor loss of hearing
- C. Observe appetite and vision deficits
- D. Changes in facial muscle control
Correct answer: A
Rationale: The correct answer is to watch for changes in emotion and behavior. The frontal lobe, particularly the left side, is responsible for regulating behavior and emotions. Therefore, following a left frontal lobe CVA, monitoring for alterations in emotion and behavior is crucial. Choices B, C, and D are incorrect because loss of hearing, appetite and vision deficits, and changes in facial muscle control are not directly associated with a left frontal lobe CVA.
4. Which of the following blood pressure parameters indicates PIH? Elevation over a baseline of:
- A. 30 mmHg systolic and/or 15 mmHg diastolic.
- B. 40 mmHg systolic and/or 20 mmHg diastolic.
- C. 10 mmHg systolic and/or 5 mmHg diastolic.
- D. 20 mmHg systolic and/or 20 mmHg diastolic.
Correct answer: A
Rationale: The correct answer is A: 30 mmHg systolic and/or 15 mmHg diastolic. These parameters indicate mild PIH (pregnancy-induced hypertension). Mild preeclampsia is characterized by an increase in systolic blood pressure greater than 30 mmHg or an increase in diastolic blood pressure greater than 15 mmHg, observed on two readings taken 6 hours apart (or reaching 140/90). Choice B (40 mmHg systolic and/or 20 mmHg diastolic) represents a more significant elevation and would indicate a more severe condition than mild PIH. Choices C (10 mmHg systolic and/or 5 mmHg diastolic) and D (20 mmHg systolic and/or 20 mmHg diastolic) do not meet the criteria for indicating PIH as they are below the accepted parameters for mild PIH.
5. One day postoperative, the client complains of dyspnea, and his respiratory rate (RR) is 35, slightly labored, and there are no breath sounds in the lower-right base. The nurse should suspect:
- A. cor pulmonale.
- B. atelectasis.
- C. pulmonary embolism.
- D. cardiac tamponade.
Correct answer: B
Rationale: The correct answer is atelectasis. The absence of breath sounds in the lower-right base is a key finding in atelectasis, which occurs when a portion of the lung collapses. The other symptoms such as dyspnea and increased respiratory rate could be present in various pulmonary conditions. Cor pulmonale is typically associated with chronic lung disease, pulmonary embolism presents with sudden onset dyspnea and chest pain, and cardiac tamponade manifests with Beck's triad of hypotension, distended neck veins, and muffled heart sounds.
