Why does the nurse instruct the client to avoid Valsalva maneuvers?
- A. Clients BP will decrease momentarily
- B. Client may lose consciousness
- C. Client may suffer from a myocardial
- D. Clients BP will increase momentarily infarction
Correct Answer: B
Rationale: The correct answer is B because performing Valsalva maneuver can lead to a sudden drop in blood pressure, causing the client to lose consciousness. This occurs due to the increased intra-abdominal pressure leading to decreased venous return to the heart. Choices A, C, and D are incorrect as they do not accurately reflect the consequences of Valsalva maneuver. Option A stating that the client's blood pressure will decrease momentarily is incorrect as it actually increases initially. Option C suggesting that the client may suffer from a myocardial infarction is incorrect as Valsalva maneuver does not directly cause heart attacks. Option D implying that the client's blood pressure will increase momentarily is also incorrect as the immediate effect is a rise followed by a significant drop.

After reviewing the database, the nurse discovers that the patient’s vital signs have not been recorded by the nursing assistive personnel (NAP). Which clinical decision should the nurse make? Administer scheduled medications assuming that the NAP would have reported
- A. abnormal vital signs. Have the patient transported to the radiology department for a scheduled x-ray, and
- B. review vital signs upon return.
- C. Ask the NAP to record the patient’s vital signs before administering medications.
- D. Omit the vital signs because the patient is presently in no distress.
Correct Answer: C
Rationale: Rationale for Choice C:
1. Safety First: Recording vital signs is crucial for patient safety. Asking the NAP to record vital signs ensures the patient's condition is monitored before administering medications.
2. Accountability: Nurses are responsible for ensuring accurate documentation of vital signs. Asking the NAP to record them maintains accountability within the healthcare team.
3. Communication: By requesting the NAP to record vital signs, the nurse fosters effective communication and collaboration in patient care.
Summary of Other Choices:
A: Administering medications without reviewing vital signs could lead to adverse effects if there are abnormalities.
B: Reviewing vital signs upon return delays immediate action and could jeopardize patient safety.
D: Omitting vital signs neglects the essential monitoring required for patient care and could result in missed opportunities for early intervention.
The most effective pharmacologic agent for the treatment of Parkinson’s disease is:
- A. Levodopa
- B. Selegilene
- C. Permax
- D. Symmetrel
Correct Answer: A
Rationale: The correct answer is A: Levodopa. Levodopa is the most effective pharmacologic agent for treating Parkinson's disease because it is converted to dopamine in the brain, replenishing the deficient dopamine levels in Parkinson's patients. Selegiline and Symmetrel are also used in treating Parkinson's, but they are typically used as adjunctive therapy rather than the primary treatment. Permax has been withdrawn from the market due to safety concerns, making it an incorrect choice.
Which of the following symptoms most likely indicates that an infusion is infiltrated?
- A. Redness at the site
- B. Pain at the site
- C. Puffiness at the site
- D. Exudate at the site
Correct Answer: C
Rationale: The correct answer is C: Puffiness at the site. This indicates infiltration of the infusion, where the medication or fluid leaks into the surrounding tissue instead of entering the bloodstream. Puffiness is a sign of fluid accumulation due to the infiltration. Redness at the site (A) may indicate infection, pain (B) can be due to various reasons, and exudate (D) may suggest infection or irritation, but they are not specific to infiltration. Infiltration assessment involves checking for swelling, coolness, and blanching around the infusion site.
A client who is scheduled for a parathyroidectomy is worried about having to wear a scarf around his neck after surgery. What nursing diagnosis should the nurse document in the care plan?
- A. Risk for impaired physical mobility due to surgery
- B. Ineffective denial related to poor coping mechanisms
- C. Disturbed body image related to the incision scar
- D. Risk of injury related to surgical outcomes
Correct Answer: C
Rationale: The correct answer is C: Disturbed body image related to the incision scar. This nursing diagnosis is appropriate as the client's concern about wearing a scarf post-surgery indicates a potential disturbance in body image due to the visible scar. The nurse should address the client's emotional response and offer support to help cope with the change in appearance.
A: Risk for impaired physical mobility due to surgery - This choice is not directly related to the client's worry about wearing a scarf and focuses more on physical limitations post-surgery.
B: Ineffective denial related to poor coping mechanisms - This choice does not address the specific body image concern expressed by the client.
D: Risk of injury related to surgical outcomes - This choice does not address the client's emotional response to the scar and focuses on physical safety risks instead.
A clinical nurse specialist (CNS) is orienting a new graduate registered nurse to an oncology unit where blood product transfusions are frequently administered. In discussing ABO compatibility, the CNS presents several hypothetical scenarios. A well-informed new graduate would know the greatest likelihood of an acute hemolytic reaction would occur when giving:
- A. A-positive blood to an A-negative client
- B. O-positive blood to an A-positive client
- C. O-negative blood to an O-positive client
- D. B-positive blood to an AB-positive client
Correct Answer: A
Rationale: The correct answer is A: A-positive blood to an A-negative client. This is because in ABO blood typing, individuals with blood type A have anti-B antibodies in their plasma. Therefore, if A-positive blood (which contains the A antigen) is given to an A-negative client (who has anti-A antibodies), there is a high risk of an acute hemolytic reaction due to the antibodies attacking the transfused blood cells.
Choices B, C, and D are incorrect because they do not involve a mismatch of ABO blood types that would lead to a significant risk of acute hemolytic reaction. In choice B, O-positive blood can be safely transfused to an A-positive client as O blood is considered the universal donor. In choice C, O-negative blood can be safely given to an O-positive client as O-negative blood is compatible with all blood types. In choice D, B-positive blood can be safely administered to an AB-positive client as the AB blood type can receive both
