Question 1 of 5
A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The nurse plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?
Correct Answer: B
Rationale: In this scenario, the correct answer is B) 150 ml/hr. To determine the correct infusion rate, we need to consider the total volume to be infused (50 ml) over the specified time (20 minutes). First, convert 20 minutes to hours (20/60 = 1/3 hr). Then, divide the total volume by the time to get the rate: 50 ml / 1/3 hr = 150 ml/hr. Option A) 75 ml/hr is incorrect because it would infuse the medication at half the required rate, which could lead to underdosing. Option C) 225 ml/hr and D) 300 ml/hr are incorrect as they would infuse the medication at a rate higher than prescribed, potentially causing adverse effects or complications for the patient. In an educational context, this question tests the nurse's ability to calculate intravenous infusion rates accurately, which is crucial in delivering safe and effective patient care. Nurses must understand medication dosages, dilutions, and infusion rates to prevent medication errors and ensure patient safety. Mastering these calculations is essential for nurses working in various healthcare settings to provide quality care and improve patient outcomes.
Question 2 of 5
A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?
Correct Answer: B
Rationale: In this scenario, the correct answer is B) 63 ml/hour. To determine the correct infusion rate, first, calculate the total volume to be infused over 4 hours (250 ml). Then, divide the total volume by the total time to get the hourly rate (250 ml / 4 hours = 62.5 ml/hour, rounded to 63 ml/hour). Option A) 13 ml/hour is incorrect because it is too slow and would not deliver the required dose within the specified time frame. Option C) 80 ml/hour and Option D) 125 ml/hour are also incorrect as they would deliver the solution too quickly, potentially causing adverse effects due to a rapid infusion rate. Educationally, this question assesses the nurse's ability to calculate and set the correct intravenous infusion rate based on the prescribed medication dosage and administration parameters. Understanding how to perform these calculations accurately is crucial for nurses to ensure safe and effective medication administration to patients. It also highlights the importance of attention to detail and precision in nursing practice.
Question 3 of 5
Which intervention is most important when caring for a client with a chest tube?
Correct Answer: D
Rationale: The most crucial intervention when caring for a client with a chest tube is to ensure that the chest tube is connected to a water-seal drainage system (D). This system helps maintain proper lung expansion and prevents complications. Keeping the drainage system at chest level (A) is important to facilitate drainage, but not as critical as ensuring the connection to the drainage system. Clamping the chest tube (B) is unnecessary and can lead to serious issues. Stripping the chest tube (C) is an outdated practice and can cause harm rather than benefit.
Question 4 of 5
During a client assessment, the healthcare provider is evaluating cranial nerve function. Which assessment finding suggests that cranial nerve II is intact?
Correct Answer: D
Rationale: In assessing cranial nerve function, specifically cranial nerve II (optic nerve), the correct answer is D) The client can read a Snellen chart from 20 feet away. This finding indicates intact visual acuity, which is directly related to the function of cranial nerve II. Option A) The client can hear a whisper from 1 to 2 feet away, pertains to cranial nerve VIII (vestibulocochlear nerve), responsible for hearing and balance. Option B) The client can identify an object by touch, refers to cranial nerve V (trigeminal nerve), involved in facial sensation and chewing. Option C) The client can shrug the shoulders against resistance, relates to cranial nerve XI (accessory nerve), responsible for neck and shoulder movements. In an educational context, understanding cranial nerve function is crucial for nurses to perform comprehensive assessments and detect neurological abnormalities. Knowing the specific functions of each cranial nerve aids in accurately identifying issues and providing appropriate care to patients. It is essential for nurses to be able to differentiate assessment findings related to various cranial nerves to ensure effective patient care and outcomes.
Question 5 of 5
The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?
Correct Answer: C
Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A), reducing air trapping (B), and slowing the respiratory rate (D) can be associated benefits, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics.
