1. A client receives a local anesthetic of Lidocaine during the repair of a skin laceration. For which of the following adverse reactions should the nurse monitor the client?
- A. Seizures
- B. Tachycardia
- C. Hypertension
- D. Fever
Correct answer: A
Rationale: Seizures are a potential adverse reaction to local anesthetics like Lidocaine. Lidocaine can affect the central nervous system and, in some cases, lead to seizure activity. Therefore, it is important for the nurse to monitor the client for any signs of seizures during and after the administration of Lidocaine.
2. When administering Lithium to a patient, what is a life-threatening side effect?
- A. Erythema
- B. Pancreatitis
- C. Seizures
- D. Headache
Correct answer: C
Rationale: When a patient is being treated with Lithium, a life-threatening side effect to watch out for is seizures. Lithium can lower the seizure threshold, increasing the risk of seizures. Seizures are serious and necessitate prompt medical intervention to ensure the patient's safety and well-being. Erythema, which is redness of the skin, is not a common life-threatening side effect of Lithium. Pancreatitis can be a side effect of Lithium, but it is not typically life-threatening. Headache is a common side effect of Lithium, but it is not considered life-threatening.
3. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?
- A. Lowered heart rate
- B. Increased myocardial contractility
- C. Decreased conduction through the AV node
- D. Vasoconstriction of renal blood vessels
Correct answer: B
Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.
4. A healthcare provider is teaching the parents of a school-age child about transdermal Methylphenidate. Which of the following instructions should the healthcare provider include?
- A. Apply one patch twice a day.
- B. Leave the patch on for 9 hours.
- C. Apply the patch to the child's waist.
- D. Use the opened tray within 6 months.
Correct answer: B
Rationale: When administering transdermal Methylphenidate, it is important to leave the patch on for 9 hours each day to ensure the medication is effective. This duration allows for proper absorption of the medication through the skin. It is crucial for parents to follow this instruction to achieve the desired therapeutic effect for their child.
5. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?
- A. PT
- B. aPTT
- C. INR
- D. Platelet count
Correct answer: B
Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.
