1. A client in a long-term care facility has Hypothyroidism and a new prescription for Levothyroxine. Which of the following dosage schedules should the nurse expect for this client?
- A. The client will start at a high dose, and the dose will be tapered as needed.
- B. The client will remain on the initial dosage during the course of treatment.
- C. The client's dosage will be adjusted daily based on blood levels.
- D. The client will start on a low dose, which will be gradually increased.
Correct answer: D
Rationale: The nurse should expect that levothyroxine will be started at a low dose and gradually increased over several weeks. This cautious approach is crucial, especially in older adult clients, to prevent toxicity and ensure optimal therapeutic outcomes for managing hypothyroidism. Choice A is incorrect because starting at a high dose and tapering as needed is not the standard approach for levothyroxine. Choice B is incorrect because the initial dosage is typically adjusted to reach the optimal therapeutic dose. Choice C is incorrect as adjusting the dosage daily based on blood levels is not necessary for levothyroxine, as it has a long half-life and requires time to reach a steady state.
2. A client with thrombophlebitis receiving heparin by continuous IV infusion asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
- A. It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.
- B. A pharmacist is the person to answer that question.
- C. Heparin does not dissolve clots. It stops new clots from forming.
- D. The oral medication you will take after this IV will dissolve the clot.
Correct answer: C
Rationale: The correct response is C. Heparin does not dissolve clots; it prevents new clots from forming. Heparin works by inhibiting the formation of new clots and the extension of existing clots, rather than directly dissolving them. The client should be informed that the purpose of heparin therapy is to prevent the clot from getting larger and to reduce the risk of new clots forming. Choices A, B, and D are incorrect. Choice A talks about reaching a therapeutic blood level of heparin, which is not related to clot dissolution. Choice B deflects the question to a pharmacist without providing relevant information. Choice D inaccurately suggests that an oral medication will dissolve the clot, which is not the mechanism of action for heparin.
3. A healthcare professional is preparing a client's medications. Which of the following actions should the professional take to follow legal practice guidelines? (Select all that apply.)
- A. Maintain skill competency.
- B. Determine the dosage.
- C. Monitor for adverse effects.
- D. Safeguard medications.
Correct answer: A
Rationale: Maintaining skill competency is a critical aspect of legal practice guidelines for healthcare professionals. It is essential to ensure that healthcare professionals are competent and up-to-date with their skills to provide safe and effective care to patients. While determining the dosage, monitoring for adverse effects, and safeguarding medications are important aspects of medication administration, maintaining skill competency is a fundamental legal responsibility that ensures the delivery of quality care. Determining the dosage and monitoring for adverse effects are clinical responsibilities, while safeguarding medications pertains to proper storage and handling, not specifically related to legal practice guidelines.
4. A healthcare professional is preparing to administer a transfusion of 300 mL of pooled platelets for a client with severe Thrombocytopenia. How should the healthcare professional plan to administer the transfusion over which of the following time frames?
- A. Within 30 minutes/unit
- B. Within 60 minutes/unit
- C. Within 2 hours/unit
- D. Within 4 hours/unit
Correct answer: A
Rationale: Platelets are fragile components that must be administered promptly to minimize the risk of clumping. The correct administration time for platelets is within 15 to 30 minutes per unit to maintain their therapeutic effectiveness and reduce adverse effects. Administering platelets over longer time frames can lead to decreased efficacy and potential harm to the patient. Therefore, the correct answer is to administer the 300 mL of pooled platelets within 30 minutes per unit.
5. When teaching a client with a prescription for Phenytoin, which of the following instructions should the nurse include?
- A. Expect the development of a mild rash.
- B. Take the medication on an empty stomach.
- C. Monitor for signs of gingival hyperplasia.
- D. Increase your intake of calcium.
Correct answer: C
Rationale: Phenytoin is known to cause gingival hyperplasia, a condition characterized by overgrowth of gum tissue. The nurse should instruct the client to monitor for signs of gingival hyperplasia, such as swollen or bleeding gums. Good oral hygiene practices are essential to prevent or manage this side effect. Choices A, B, and D are incorrect. Phenytoin does not typically cause a mild rash, should be taken with food to reduce gastrointestinal upset, and does not warrant an increase in calcium intake.
