Nokea
Which of the following findings should the nurse identify as a contraindication to receiving this alternative therapy?
- A. Headaches
- B. Lymphedema
- C. Mouth sores
- D. Urticaria
Correct Answer: B
Rationale: The correct answer is B: Lymphedema. Lymphedema is a swelling caused by a lymphatic system blockage, which can be worsened by some alternative therapies. Headaches, mouth sores, and urticaria are symptoms that may not necessarily contraindicate alternative therapy. Lymphedema can cause complications if not managed properly, making it a clear contraindication.

A nurse is caring for a client who has a peripherally inserted central catheter (PICC) line in her left forearm. The client is receiving an antibiotic via intermittent IV bolus every 12 hr. Which of the following actions should the nurse take in managing the client's PICC line?
- A. Access the catheter using a non-coring needle.
- B. Change the transparent membrane dressing daily.
- C. Maintain a continuous IV infusion through the PICC line.
- D. Flush the catheter with a 0.9% sodium chloride solution after each use.
Correct Answer: D
Rationale: Correct Answer: D - Flush the catheter with a 0.9% sodium chloride solution after each use.
Rationale: Flushing the catheter with 0.9% sodium chloride solution after each use helps prevent clot formation, maintains patency, and ensures proper functioning of the PICC line. This action also helps prevent infection and occlusions.
Incorrect Choices:
A: Accessing the catheter using a non-coring needle is not necessary for routine care of a PICC line.
B: Changing the transparent membrane dressing daily may increase the risk of infection and disrupt the integrity of the dressing.
C: Maintaining a continuous IV infusion through the PICC line is not indicated for a client receiving intermittent IV bolus antibiotics.
E, F, G: No additional choices provided.
A nurse is caring for a client who is experiencing diabetic ketoacidosis (DKA). Which of the following is the priority intervention by the nurse?
- A. Check potassium levels.
- B. Begin bicarbonate continuous IV infusion.
- C. Initiate a continuous IV insulin infusion.
- D. Administer 0.9% sodium chloride.
Correct Answer: D
Rationale: The correct answer is D: Administer 0.9% sodium chloride. The priority intervention in DKA is fluid resuscitation to correct dehydration and electrolyte imbalances. 0.9% sodium chloride helps restore intravascular volume and improves kidney perfusion. Checking potassium levels (A) is important but can wait until after fluid resuscitation. Beginning bicarbonate infusion (B) is not recommended as it can worsen acidosis. Initiating continuous IV insulin infusion (C) is important but should follow fluid resuscitation. Administering 0.9% sodium chloride takes precedence in managing DKA.
A nurse is monitoring an older adult client who has an exacerbation of chronic lymphocytic leukemi The nurse notes petechiae on the client's skin. Which of the following actions should the nurse take?
- A. Determine the client's blood type.
- B. Avoid administering IV pain medication.
- C. Institute bleeding precautions.
- D. Implement airborne precautions.
Correct Answer: C
Rationale: The correct answer is C: Institute bleeding precautions. Petechiae are tiny red or purple spots on the skin caused by bleeding under the skin. In chronic lymphocytic leukemia, the client's platelet count may be low, leading to an increased risk of bleeding. By instituting bleeding precautions, the nurse can help prevent injuries that could result in further bleeding. Determining the client's blood type (A) is not necessary in this situation. Avoiding IV pain medication (B) is not directly related to managing petechiae. Implementing airborne precautions (D) is not relevant to the client's presentation with petechiae.
A nurse is preparing to obtain a guaiac smear sample from a client for fecal occult blood testing. Which of the following actions should the nurse plan to take?
- A. Take the sample from the outer edge of formed stool.
- B. Wear sterile gloves when collecting the sample.
- C. Collect three samples from a single bowel movement.
- D. Discard samples that contain urine.
Correct Answer: D
Rationale: The correct answer is D: Discard samples that contain urine. This is crucial because urine can interfere with the accuracy of the fecal occult blood test results, leading to false positives. By discarding samples that contain urine, the nurse ensures the reliability of the test.
A: Taking the sample from the outer edge of formed stool is not necessary for a guaiac smear sample.
B: Wearing sterile gloves is important for infection control but not specifically for collecting a guaiac smear sample.
C: Collecting three samples from a single bowel movement is not standard practice for fecal occult blood testing and may not be necessary.
E, F, G: No further options provided.
A nurse is caring for a client who is postoperative and develops respiratory depression after receiving morphine for pain control. Which of the following medications should the nurse expect the provider to prescribe?
- A. Flumazenil
- B. Calcium gluconate
- C. Diphenhydramine
- D. Naloxone
Correct Answer: D
Rationale: The correct answer is D: Naloxone. Naloxone is an opioid antagonist that reverses the effects of opioids, including respiratory depression. Therefore, the nurse should expect the provider to prescribe naloxone to counteract the respiratory depression caused by morphine. Flumazenil (A) is a benzodiazepine antagonist and would not be effective in this situation. Calcium gluconate (B) is used to treat calcium deficiencies and would not address respiratory depression. Diphenhydramine (C) is an antihistamine and not indicated for reversing opioid-induced respiratory depression.
