Which of the following measures is not recommended to prevent pressure ulcers?
- A. Massaging the reddened area with lotion
- B. Using a water or air mattress
- C. Adhering to a schedule for positioning and turning
- D. Providing meticulous skin care
Correct Answer: A
Rationale: Massaging a reddened area can cause further tissue damage by increasing pressure on already compromised skin. The other options, such as using specialized mattresses, adhering to repositioning schedules, and maintaining good skin care, are all recommended strategies to prevent pressure ulcers by reducing pressure and friction on vulnerable areas of the skin.

The physician orders a maintenance dose of 5,000 units of subcutaneous heparin (an anticoagulant) daily. Nursing responsibilities for Mrs. Mitchell now include:
- A. Reviewing daily activated partial thromboplastin time (APTT) and prothrombin time.
- B. Reporting an APTT above 45 seconds to the physician
- C. Assessing the patient for signs and symptoms of frank and occult bleeding
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D. When a physician orders a maintenance dose of subcutaneous heparin, nursing responsibilities include reviewing daily activated partial thromboplastin time (APTT) and prothrombin time to monitor the patient's coagulation status, reporting an APTT above 45 seconds to the physician as it may indicate a risk of bleeding, and assessing the patient for signs and symptoms of frank and occult bleeding, which are potential adverse effects of anticoagulant therapy. Therefore, all the options listed are essential nursing responsibilities when a patient is on subcutaneous heparin therapy.
Which of the following interventions is considered the most effective form of universal precautions?
- A. Cap all used needles before removing them from their syringes
- B. Discard all used uncapped needles and syringes in an impenetrable protective container
- C. Wear gloves when administering IM injections
- D. Follow enteric precautions
Correct Answer: B
Rationale: The most effective form of universal precautions is to discard all used uncapped needles and syringes in an impenetrable protective container. This practice minimizes the risk of needle-stick injuries, which are a significant concern when dealing with used needles. By safely disposing of uncapped needles, healthcare providers can protect themselves and others from potential exposure to bloodborne pathogens.
Which of the following blood tests should be performed before a blood transfusion?
- A. Prothrombin and coagulation time
- B. Blood typing and cross-matching
- C. Bleeding and clotting time
- D. Complete blood count (CBC) and electrolyte levels
Correct Answer: B
Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.
Which of the following vascular system changes result from aging?
- A. Increased peripheral resistance of the blood vessels
- B. Decreased blood flow
- C. Increased workload of the left ventricle
- D. All of the above
Correct Answer: D
Rationale: As individuals age, various changes occur in the vascular system. These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.
A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:
- A. Infection
- B. Hypothermia
- C. Anxiety
- D. Dehydration
Correct Answer: D
Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.
