1. When choosing a needle gauge for an intramuscular injection in a 12-year-old boy, which of the following gauges would you choose?

• A. 27 gauge
• B. 25 gauge
• C. 22 gauge
• D. 20 gauge

Correct answer: C

Rationale: The correct answer is 22 gauge. A 22-gauge needle is recommended for school-age children, toddlers, and adolescents due to their muscle mass and tolerance. In infants, a smaller gauge (23-25) is preferred as their muscles are less developed and more sensitive. Choice A, 27 gauge, is too thin for an intramuscular injection in a 12-year-old boy. Choice B, 25 gauge, is more suitable for infants than for a 12-year-old. Choice D, 20 gauge, is too thick and not typically used for intramuscular injections in children.

2. A client who has a known history of cardiac problems and is still smoking enters the clinic complaining of sudden onset of sharp, stabbing pain that intensifies with a deep breath. The pain is occurring on only one side and can be isolated upon general assessment. The nurse concludes that this description is most likely caused by:

• A. pleurisy.
• B. pleural effusion.
• C. atelectasis.
• D. tuberculosis.

Correct answer: A

Rationale: Pleurisy is an inflammation of the pleura and is often accompanied by an abrupt onset of pain. Symptoms of pleurisy include sudden sharp, stabbing pain that is usually unilateral and localized to a specific portion of the chest. The pain can be exacerbated by deep breathing. In contrast, pleural effusion is characterized by fluid accumulation in the pleural space, not sharp pain. Atelectasis involves collapse or closure of a lung leading to reduced gas exchange, but it does not typically present with sharp, stabbing pain. Tuberculosis is a bacterial infection that can affect the lungs but does not typically manifest with sudden sharp pain exacerbated by deep breathing.

3. The nurse is caring for a client receiving warfarin therapy (Coumadin�) following a stroke. The client's PT/INR was completed at 7:00 A.M. prior to the morning meal with an INR reading of 4.0. Which of the following is the nurse's first priority?

• A. Call the physician to request an increase in the Coumadin� dose.
• B. Administer a vitamin K injection IM and notify the physician of the results.
• C. Assess the client for bleeding around the gums or in the stool and notify the physician of the lab results and latest dose of Coumadin�.
• D. Notify the next shift to hold the daily dose of Coumadin� scheduled for 5:00 P.M.

Correct answer: B

Rationale: In a client receiving warfarin therapy with a high INR of 4.0, the nurse's first priority is to administer a vitamin K injection intramuscularly (IM) and notify the physician of the results. An INR of 4.0 indicates excessive anticoagulation, putting the client at risk of bleeding. Vitamin K is the antidote for warfarin overdose and helps to reverse its effects. It is crucial to administer vitamin K promptly to prevent bleeding complications. Calling the physician to request an increase in the Coumadin� dose is inappropriate and dangerous in this situation, as it would further raise the INR. Assessing the client for bleeding and notifying the physician is important but not the first priority when faced with a critically high INR. Holding the daily dose of Coumadin� may be necessary after administering vitamin K, but it is not the primary action needed to address the acute high INR level.

4. What is the next step for a 64-year-old male diagnosed with COPD and CHF who shows a 10 lbs increase in total body weight over the last few days?

• A. Contact the patient's physician immediately.
• B. Check the intake and output on the patient's flow sheet.
• C. Encourage the patient to ambulate to reduce lower extremity edema.
• D. Check the patient's vitals every 2 hours.

Correct answer: B

Rationale: In a patient with COPD and CHF experiencing a sudden increase in total body weight, the priority is to check the intake and output on the patient's flow sheet to evaluate fluid balance. This assessment helps determine if the weight gain is due to fluid retention, which can exacerbate CHF. Contacting the physician may be necessary based on the intake and output findings. While encouraging ambulation is beneficial for circulation, it may not address the root cause of fluid retention. Checking vitals every 2 hours is important for monitoring stability but may not pinpoint the reason behind the weight gain.

5. Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:

• A. it is chemically stable, nonallergenic, and can be administered orally once a day.
• B. it is available in a wide range of concentrations to meet individual client requirements.
• C. it is a prodrug of T3.
• D. it has a long half-life.

Correct answer: A

Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.
