1. A postoperative client has three different PRN analgesics prescribed for varying levels of pain. The nurse inadvertently administers a dose that is not within the prescribed parameters. What action should the nurse take first?
- A. Assess for side effects of the medication.
- B. Document the client’s responses.
- C. Complete a medication error report.
- D. Determine if the pain was relieved.
Correct answer: A
Rationale: In the scenario where a nurse administers a medication outside the prescribed parameters, the immediate action should be to assess the client for any potential side effects of the medication. This is crucial to ensure the client's safety and well-being. By promptly assessing for side effects, the nurse can address any adverse reactions promptly and provide necessary interventions. Once the client's safety is ensured, documenting the client's responses, completing a medication error report, and assessing pain relief can follow as part of the broader response to the medication error. Choice B is not the first priority because the immediate concern is the potential harm from the incorrect dose. Choice C is also important but comes after ensuring the client's safety. Choice D focuses on the outcome rather than the immediate need to address any side effects of the medication.
2. The father of an 11-year-old client reports to the nurse that the client has been 'wetting the bed' since the passing of his mother and is concerned. Which action is most important for the nurse to take?
- A. Reassure the father that it is normal for a child to wet the bed after a traumatic event
- B. Inform the father that nocturnal emissions are abnormal and his son is developmentally delayed
- C. Inform the father that it is crucial to let the son know that bedwetting is a normal response to trauma
- D. Refer the father and the client to a psychologist
Correct answer: C
Rationale: Bedwetting after trauma, such as losing a parent, is common in children. The nurse should inform the father that it is crucial to let the son know that bedwetting is a normal response to trauma. Reassurance and understanding are essential in addressing the child's emotional needs during this difficult time. Choice A is incorrect as it focuses on puberty rather than trauma as the underlying cause. Choice B is incorrect as it provides inaccurate information about nocturnal emissions and developmental delay. Choice D is premature as the first step should be to provide education and support before considering a referral to a psychologist.
3. The healthcare professional counts an adult's apical heartbeat at 110 beats per minute. The healthcare professional describes this as:
- A. Asystole
- B. Bigeminy
- C. Tachycardia
- D. Bradycardia
Correct answer: C
Rationale: Tachycardia is a heart rate greater than 100 beats per minute. In this case, an adult's heart rate of 110 beats per minute falls within the range of tachycardia. Tachycardia can be a common physiological response to various stresses on the body, leading to an increased heart rate. Asystole refers to the absence of cardiac activity, bigeminy is a specific heart rhythm pattern, and bradycardia is a heart rate below 60 beats per minute in adults.
4. Which instruction is most important for the nurse to include when teaching a client with limited mobility strategies to prevent venous thrombosis?
- A. Perform cough and deep breathing exercises hourly.
- B. Turn from side to side in bed at least every 2 hours.
- C. Dorsiflex and plantarflex the feet 10 times each hour.
- D. Drink approximately 4 ounces of water every hour.
Correct answer: C
Rationale: The most crucial instruction for a client with limited mobility to prevent venous thrombosis is to perform dorsiflexion and plantarflexion of the feet 10 times each hour. These exercises help promote venous return, reducing the risk of thrombosis by preventing blood stasis in the lower extremities. While other measures like turning in bed and staying hydrated are beneficial, promoting venous return through foot exercises is the priority in preventing venous thrombosis in clients with limited mobility. Dorsiflexion and plantarflexion directly target the calf muscle pump, aiding in the circulation of blood back to the heart and preventing clot formation. The other options, such as cough and deep breathing exercises, turning in bed, and hydration, are important for overall health but do not directly address venous stasis and thrombosis prevention in the same way as foot exercises.
5. Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?
- A. Superficial veins are more easily found in the feet and ankles.
- B. A decreased flow rate could lead to thrombosis formation.
- C. It is more challenging to move a cannulated extremity when using the leg or foot.
- D. Veins in the feet and ankles are located deep, making the procedure more painful.
Correct answer: B
Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.
