Nursing Elites

1. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

2. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?

• A. Consuming a high-fat diet
• B. Using tanning beds
• C. Smoking cigarettes
• D. Drinking alcohol

Correct answer: B

Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.

3. A nurse is preparing to administer an intramuscular injection to a client. Which action should the nurse take to reduce the client's risk of injury?

• A. Use a 1-inch needle
• B. Select a large muscle for the injection
• C. Aspirate for blood return before injecting
• D. Massage the injection site

Correct answer: C

Rationale: The correct answer is to aspirate for blood return before injecting. This action helps ensure that the needle is not in a blood vessel, reducing the risk of injury. Using a 1-inch needle (Choice A) is a standard length for intramuscular injections but does not directly reduce the risk of injury. Selecting a large muscle for the injection (Choice B) is important for proper medication absorption but does not directly reduce the risk of injury. Massaging the injection site (Choice D) can help with medication absorption but does not reduce the risk of injury.

4. The mother of a 6-year-old anemic boy is taught by the nurse to give iron supplements. Which statement indicates that the mother understands the proper administration of iron?

• A. The iron tablets will be absorbed between meals, on an empty stomach
• B. I should give the iron tablets with his milk and cereal each morning
• C. Iron preparations can be taken with antibiotics if he develops an infection
• D. The iron tablets may cause him to sunburn more easily so he should wear sunscreen

Correct answer: A

Rationale: The correct answer is A because iron supplements are best absorbed on an empty stomach, which maximizes their effectiveness. Giving iron tablets with milk or calcium-rich foods, as mentioned in choice B, should be avoided as they can decrease iron absorption. Choice C is incorrect because iron preparations should not be taken with antibiotics due to potential interactions. Choice D is also incorrect as iron tablets do not cause an increased risk of sunburn, so sunscreen is not necessary specifically due to iron supplementation.

5. A nurse is planning care for a client who has a new prescription for metoprolol (Lopressor). Which assessment finding should the nurse report to the healthcare provider before administering the medication?

• A. Heart rate of 50 beats per minute
• B. Blood pressure of 90/60 mm Hg
• C. Respiratory rate of 20 breaths per minute
• D. Temperature of 99°F (37.2°C)

Correct answer: A

Rationale: A heart rate of 50 beats per minute is a concerning finding that should be reported before administering metoprolol. Metoprolol is a beta-blocker that can further lower the heart rate, so a heart rate of 50 bpm indicates potential bradycardia, which is a contraindication for administering this medication. Choices B, C, and D are within normal ranges and do not pose immediate concerns related to metoprolol administration.
