A client is scheduled for a prostatectomy, and the anesthesiologist plans to use a spinal (sub-arachnoid) block during surgery. In the operating room, the nurse positions the client according to the anesthesiologist’s instructions. Why does the client require special positioning for this type of anesthesia?
- A. To prevent confusion
- B. To prevent cerebrospinal fluid (CSF) leakage
- C. To prevent seizures
- D. To prevent cardiac arrhythmias
Correct Answer: B
Rationale: The correct answer is B: To prevent cerebrospinal fluid (CSF) leakage.
1. Positioning is crucial to prevent CSF leakage as the spinal block is administered into the sub-arachnoid space where CSF is present.
2. Incorrect Answers:
A: Positioning is not related to preventing confusion in this context.
C: Seizures are not typically associated with spinal block anesthesia.
D: Cardiac arrhythmias are not directly impacted by the client's positioning for a spinal block.

Through which of the ff body fluids has transmission of HIV been established? Choose all that apply
- A. Saliva
- B. Sweat
- C. Tears f. Breastmilk
- D. Blood g. Urine
Correct Answer: C
Rationale: The correct answer is C: Tears and F: Breastmilk. HIV transmission has been established through breastmilk due to the presence of the virus in the milk. Tears can also transmit HIV if they contain blood from an HIV-positive individual. Saliva, sweat, and urine do not typically contain enough HIV to transmit the virus. Blood is a well-known mode of HIV transmission due to the high viral load present in blood. Therefore, choices A, B, D, and G are incorrect as they do not have sufficient levels of the virus to transmit HIV.
An adult has and IV line in the right forearm infusing D5 ½ NS with 20 mEq of potassium at 75 ml/h. which statement would be a correct report from the RN?
- A. The potassium bag is piggybacked into the dextrose at 75ml/h
- B. The clamp should be closed below the D5 ½ NS bag
- C. Potassium is on the secondary line
- D. 75 ml infuse in one hour
Correct Answer: C
Rationale: Correct Answer: C
Rationale:
1. Potassium is typically administered on a secondary line to prevent rapid infusion and potential adverse effects.
2. The primary line carries the D5 ½ NS solution without potassium, while the secondary line delivers the potassium.
3. Reporting that "potassium is on the secondary line" accurately describes the setup for this IV infusion.
Summary:
A: Incorrect - Incorrectly states that the potassium bag is piggybacked into the dextrose.
B: Incorrect - Closing the clamp below the D5 ½ NS bag is unnecessary and does not address the potassium infusion.
D: Incorrect - Fails to address the specific issue of the potassium infusion being on a secondary line.
Which of the following signs indicates to the nurse that digoxin (Lanoxin) has been effective for a patient?
- A. Urine output decreases
- B. Heart rate higher than 95
- C. Urine output increases
- D. Heart rate lower than 50
Correct Answer: C
Rationale: The correct answer is C: Urine output increases. This indicates digoxin's effectiveness as it improves cardiac output by enhancing contraction strength. Increased urine output signifies improved kidney perfusion due to enhanced cardiac function. Option A is incorrect as decreased urine output indicates poor kidney perfusion. Option B is incorrect as digoxin aims to regulate heart rate, not necessarily make it higher than 95. Option D is incorrect as a heart rate lower than 50 could indicate digoxin toxicity.
Which method of data collection will the nurse use to establish a patient’s database?
- A. Reviewing the current literature to determine evidence-based nursing actions
- B. Checking orders for diagnostic and laboratory tests
- C. Performing a physical examination
- D. Ordering medications
Correct Answer: C
Rationale: The correct answer is C because performing a physical examination is the method nurses use to establish a patient's database. This involves directly assessing the patient's physical condition, gathering data on their health status, and identifying any abnormalities or concerns. Reviewing literature (A) is important but not a direct method of collecting patient data. Checking orders for tests (B) is part of data collection but not the initial step. Ordering medications (D) is a treatment action, not data collection.
The nurse is performing an assessment of a client who has a small wound on the knee, collecting cues about the client’s health status. Which of the following would the nurse identify as a subjective cue?
- A. Sharp pain in the knee
- B. Small bloody drainage on dressing
- C. Temperature of 102 degrees F
- D. Pulse rate of 90 beats per minute
Correct Answer: A
Rationale: The correct answer is A because sharp pain is a subjective cue as it is based on the client's personal experience and perception. The client is the only one who can report the presence and intensity of pain.
B: Small bloody drainage is an objective cue that can be observed and measured by the nurse.
C: Temperature of 102 degrees F is an objective cue that can be measured using a thermometer.
D: Pulse rate of 90 beats per minute is an objective cue that can be measured using a pulse oximeter.
In summary, subjective cues are based on the client's feelings and perceptions, while objective cues are observable and measurable by the healthcare provider.
