Nursing Elites

1. Which method is used to verify the placement of a newly inserted central venous access device (CVAD)?

• A. Chest x-ray
• B. Flushing the line with heparin
• C. Withdrawing blood to ensure patency
• D. Chest fluoroscopy

Correct answer: A

Rationale: The correct method to verify the placement of a newly inserted central venous access device (CVAD) is a chest x-ray. This is crucial to detect any potential complications such as pneumothorax, which can occur during subclavian vein catheter insertion. Symptoms of pneumothorax may include shortness of breath and anxiety. Flushing the line with heparin is not used for placement verification, but rather for maintaining patency after verification. Withdrawing blood to ensure patency is done after placement is confirmed, not for initial verification. Chest fluoroscopy may be used during the insertion process but is not typically employed for placement verification.

2. The nurse transcribes the postoperative prescriptions for a client who returns to the unit following surgery and notes that an antihypertensive medication that was prescribed preoperatively is not listed. Which action should the nurse take?

• A. Consult with the pharmacist about the need to continue the medication.
• B. Administer the antihypertensive medication as prescribed preoperatively.
• C. Withhold the medication until the client is fully alert and vital signs are stable.
• D. Contact the health care provider to renew the prescription for the medication.

Correct answer: D

Rationale: In this scenario, the nurse has noted that an antihypertensive medication prescribed preoperatively is missing from the postoperative prescriptions. It is essential to renew preoperative medications postoperatively. Therefore, the correct action for the nurse to take is to contact the health care provider to renew the prescription for the antihypertensive medication. Consulting with the pharmacist about the need to continue the medication is not appropriate in this situation as pharmacists do not prescribe or renew medications. Administering the antihypertensive medication as prescribed preoperatively without a current prescription poses a risk to the client's safety. Withholding the medication until the client is fully alert and vital signs are stable does not address the issue of the missing prescription and delays the client's necessary treatment.

3. A mother complains to the nurse that her 3-year-old child refuses to go to preschool. The child rarely interacts and avoids playing with other children. Which statement would the nurse provide?

• A. Do not be concerned because all toddlers behave this way.
• B. Ask the teacher to push the child to speak up and open up to the other kids.
• C. Set boundaries and supervise the child closely.
• D. Give your child time to get acquainted and warm up to the new environment.

Correct answer: D

Rationale: According to the mother's description, the child is a slow-to-warm-up child. These children are uneasy in new situations or with unfamiliar people. The nurse would educate the mother to give the child time to be more familiar with the new environment. All toddlers do not behave in the same manner. A slow-to-warm-up child should not be pressured to do anything against his or her wishes. Setting boundaries and closely supervising the child is not the best approach for a child who needs time to adapt. Asking the teacher to push the child to open up can create more anxiety and stress for the child, which is not recommended.

4. Which therapeutic approach would indicate the client is receiving desensitization therapy?

• A. Imagery
• B. Modeling
• C. Role playing
• D. Assertiveness training

Correct answer: A

Rationale: The correct answer is 'Imagery.' Imagery is a therapeutic approach used in desensitization therapy. It helps in facilitating positive self-talk and involves the client initiating and controlling mental pictures to correct faulty cognitions. Modeling, role-playing, and assertiveness training are effective general behavioral approaches but are not specific to desensitization therapy.

5. Which instruction is most important for the nurse to include when teaching a client with limited mobility strategies to prevent venous thrombosis?

• A. Perform cough and deep breathing exercises hourly.
• B. Turn from side to side in bed at least every 2 hours.
• C. Dorsiflex and plantarflex the feet 10 times each hour
• D. Drink approximately 4 ounces of water every hour

Correct answer: C

Rationale: To reduce the risk of venous thrombosis, the nurse should instruct the client to perform dorsiflexion and plantar flexion exercises regularly. These exercises help promote venous return and prevent venous thrombus formation. Options A, B, and D are beneficial in managing other complications of immobility, such as atelectasis and pressure ulcers, but they are less effective in preventing venous thrombosis compared to dorsiflexion and plantar flexion exercises.
