Nursing Elites

1. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.

2. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which intervention should the nurse implement first?

• A. Administer regular insulin IV.
• B. Administer IV fluids at 250 ml/hr.
• C. Administer sodium bicarbonate IV push.
• D. Administer furosemide (Lasix) IV push.

Correct answer: A

Rationale: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.

3. During a clinic visit, the mother of a 7-year-old reports to the nurse that her child is often awake until midnight playing and is then very difficult to awaken in the morning for school. Which assessment data should the nurse obtain in response to the mother's report?

• A. The occurrence of any episodes of sleep apnea
• B. The child's blood pressure, pulse, and respirations
• C. Length of rapid eye movement (REM) sleep that the child is experiencing
• D. Description of the family's home environment

Correct answer: D

Rationale: In response to the mother's report, the nurse should assess the family's home environment first to identify any factors that may hinder the establishment of bedtime routines conducive to sleep. Factors such as noise, light, distractions, or other environmental aspects could be contributing to the child's difficulty falling asleep at a reasonable hour and waking up in the morning.

4. During a client assessment, the healthcare provider is evaluating cranial nerve function. Which assessment finding suggests that cranial nerve II is intact?

• A. The client can hear a whisper from 1 to 2 feet away.
• B. The client can identify an object by touch.
• C. The client can shrug the shoulders against resistance.
• D. The client can read a Snellen chart from 20 feet away.

Correct answer: D

Rationale: The ability to read a Snellen chart from 20 feet away indicates intact cranial nerve II (optic nerve), responsible for vision. Hearing a whisper (A) is associated with cranial nerve VIII (vestibulocochlear nerve), identifying an object by touch (B) is related to cranial nerves V (trigeminal nerve) and VII (facial nerve), and shoulder shrugging against resistance (C) is a test for cranial nerve XI (accessory nerve). Thus, the correct answer is D as it specifically tests the function of cranial nerve II.

5. What action should the nurse take after applying gloves to irrigate a client's indwelling urinary catheter using an open technique?

• A. Empty the client's urinary drainage bag.
• B. Draw up the irrigating solution into the syringe.
• C. Secure the client's catheter to the drainage tubing.
• D. Use aseptic technique to instill the irrigating solution.

Correct answer: B

Rationale: After applying gloves to irrigate an indwelling urinary catheter using an open technique, the next step for the nurse is to draw up the irrigating solution into the syringe. This step is crucial as it ensures that the solution is ready to be instilled through the catheter to maintain its patency and prevent blockages. Option A is incorrect as emptying the client's urinary drainage bag is not the immediate next step in the irrigation process. Option C is incorrect as securing the client's catheter to the drainage tubing is not necessary at this stage. Option D is incorrect as the question pertains to the action immediately after applying gloves and does not involve instilling the irrigating solution yet.
