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. An angry client screams at the emergency department triage nurse, “I’ve been waiting here for two hours! You and the staff are incompetentâ€. What is the best response for the nurse to make?
- A. The emergency department is very busy at this time.
- B. I’ll let you see the doctor next because you’ve waited so long.
- C. I’m doing the best I can for the sickest clients first.
- D. I understand you are frustrated with the wait time.
Correct answer: D
Rationale: Correct Answer: The best response for the nurse is to choose option D, 'I understand you are frustrated with the wait time.' This response demonstrates empathy and validates the client's feelings, helping to defuse the situation. Choice A is not the best response as it does not directly address the client's emotions or concerns. Choice B is inappropriate as it gives preferential treatment based on the client's behavior. Choice C, while true, does not acknowledge the client's frustration or offer empathy.
3. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
4. An adolescent male client is admitted to the hospital. Based on Erikson’s theory of psychosocial development, which nursing intervention best assists this adolescent’s adjustment to his hospital stay?
- A. Invite him to participate in the evening group activity
- B. Schedule frequent private phone calls to his parents
- C. Provide access to a variety of video games in his room
- D. Encourage him to learn his way around the hospital
Correct answer: A
Rationale: Inviting the adolescent to participate in group activities aligns with Erikson's theory of psychosocial development, specifically the stage of developing social relationships. By engaging in group activities, the adolescent can interact with peers, fostering social skills and aiding in adjustment to the hospital environment. Choice B is incorrect as excessive reliance on phone calls to parents may hinder the adolescent's autonomy and independence, which are crucial aspects of Erikson's theory for this age group. Choice C, providing access to video games, while potentially offering entertainment, does not directly address the need for social interaction and relationship-building. Choice D, encouraging the adolescent to learn his way around the hospital, is important for familiarity but may not directly address the need for social interaction and adjustment in the hospital setting.
5. The client has silvery scaling plaques bilaterally on elbows, forearms, and palms. When scratched, the skin bleeds over these plaques. What is most important to include in this client’s plan of care?
- A. Interventions to decrease emotional stress
- B. Precautions about avoiding sunlight
- C. Strategies to increase omega-3 fatty acids in the diet
- D. Instruct about applying a corticosteroid cream
Correct answer: A
Rationale: The most important aspect to include in this client's plan of care is interventions to decrease emotional stress. Psoriasis, characterized by silvery scaling plaques on the skin, can be exacerbated by emotional stress. Managing stress is crucial in controlling the condition. Precautions about avoiding sunlight are important in psoriasis management, but emotional stress has a more significant impact. While omega-3 fatty acids may provide some benefits, stress management should take priority. Applying a corticosteroid cream may help with symptoms, but addressing emotional stress is crucial for long-term management of psoriasis.
