1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?
- A. To reduce abdominal pressure on the diaphragm
- B. To promote retraction of the intercostal accessory muscles of respiration
- C. To promote bronchodilation and effective airway clearance
- D. To decrease pressure on the medullary center which stimulates breathing
Correct answer: A
Rationale: Elevating the head of the bed to 30 degrees is done to reduce abdominal pressure on the diaphragm, aiding in lung expansion and oxygenation. This position helps improve respiratory mechanics by allowing the diaphragm to move more effectively. Choice B is incorrect as elevating the head of the bed does not directly promote retraction of the intercostal accessory muscles of respiration. Choice C is incorrect because although elevating the head of the bed can assist with airway clearance, its primary purpose in ARDS is to decrease pressure on the diaphragm. Choice D is incorrect because reducing pressure on the medullary center is not the main goal of elevating the head of the bed; the focus is on enhancing lung function and oxygen exchange.
2. A client complains of paresthesia in the fingers and toes and experiences hand spasms when the blood pressure cuff is inflated. Which serum laboratory finding should the nurse expect to find when assessing the client?
- A. Elevated serum calcium
- B. Low serum magnesium
- C. Low serum calcium
- D. Elevated serum potassium
Correct answer: C
Rationale: The correct answer is C: Low serum calcium. Hand spasms and paresthesia are indicative of potential hypocalcemia, which is characterized by low serum calcium levels. Elevated serum calcium (Choice A) is not consistent with the symptoms described. Low serum magnesium (Choice B) and elevated serum potassium (Choice D) are not typically associated with hand spasms and paresthesia.
3. After receiving report, which client should the nurse assess last?
- A. An older client with dark red drainage on a postoperative dressing, but no drainage in the Hemovac
- B. An adult client with no postoperative drainage in the Jackson-Pratt drain with the bulb compressed
- C. An older client with a distended abdomen and no drainage from the nasogastric tube
- D. An adult client with rectal tube draining clear pale red liquid drainage
Correct answer: D
Rationale: The correct answer is D because the client with rectal tube drainage of clear pale red liquid is likely to be the least urgent since this is a normal post-operative finding. Clear pale red liquid drainage from a rectal tube is typically not a cause for immediate concern. Choices A, B, and C present clients with concerning signs that may require more immediate assessment and intervention. A client with dark red drainage on a postoperative dressing may indicate active bleeding, a client with a compressed Jackson-Pratt drain bulb may have inadequate drainage resulting in complications, and a client with a distended abdomen and no drainage from the nasogastric tube may be experiencing gastrointestinal issues that need prompt evaluation.
4. A client is being treated for minor injuries following an automobile accident in which the only other passenger was killed. The client asks the nurse, 'Is my friend who was in the car with me ok?' What response is best for the nurse to provide?
- A. I am sorry, but your friend was killed in the accident.
- B. Right now you need to concentrate on getting well.
- C. Was the passenger in the car your friend?
- D. I think your friend is going to be all right.
Correct answer: A
Rationale: The correct answer is A: 'I am sorry, but your friend was killed in the accident.' In this situation, honesty and compassion are essential. The nurse should provide the client with truthful information, acknowledging the client's need to know the reality of the situation. Choice B is dismissive and does not address the client's inquiry directly. Choice C is a deflecting question and does not offer the direct information the client is seeking. Choice D provides false reassurance, which is not appropriate in this circumstance where the reality needs to be communicated.
5. Which medication should the nurse anticipate administering to a client who is diagnosed with myxedema coma?
- A. Intravenous administration of thyroid hormones
- B. Oral administration of hypnotic agents
- C. Intravenous bolus of hydrocortisone
- D. Subcutaneous administration of vitamin K
Correct answer: A
Rationale: The correct answer is A: Intravenous administration of thyroid hormones. Myxedema coma is a severe form of hypothyroidism that necessitates immediate replacement of thyroid hormones. Administering thyroid hormones intravenously ensures rapid absorption and effectiveness in managing the condition. Choice B, oral administration of hypnotic agents, is incorrect as it does not address the primary issue of thyroid hormone deficiency in myxedema coma. Choice C, intravenous bolus of hydrocortisone, is not the appropriate treatment for myxedema coma as adrenal insufficiency is not the primary concern in this condition. Choice D, subcutaneous administration of vitamin K, is unrelated to the management of myxedema coma and does not address the underlying thyroid hormone deficiency that characterizes this condition.
