A patient who takes oral levothyroxine for hypothyroidism is admitted to the hospital. After the provider determines the patient has myxedema, what action will the provider take?

Correct Answer: C

Rationale: The correct answer is C: Change to intravenous levothyroxine. In myxedema crisis, the patient is severely hypothyroid and unable to absorb oral medications. Intravenous levothyroxine is the most effective route in this situation, as it bypasses the gastrointestinal tract. Option A (Prescribe a B-blocker) is incorrect as it does not address the underlying hypothyroidism. Option B (Increase the dose of levothyroxine) is not appropriate in myxedema crisis due to impaired absorption. Option D (Prescribe methimazole) is used for hyperthyroidism, not hypothyroidism.

Correct Answer: D

Rationale: The correct answer is D, Glargine (Lantus), because it is a long-acting insulin that provides a steady release of insulin over a 24-hour period. Glargine has a duration of action of up to 24 hours, making it suitable for once-daily dosing. Isophane NPH (Humalin N), choice A, is an intermediate-acting insulin with a duration of action of around 12-16 hours. Insulin glulisine (Apidra) and Insulin Aspart (Novolog), choices B and C, are rapid-acting insulins with a quicker onset and shorter duration of action compared to long-acting insulins like Glargine.

Correct Answer: D

Rationale: The correct answer is D. Patients taking stimulant drugs for ADHD may lose weight due to appetite suppression as a common side effect. This statement indicates understanding of the teaching because it reflects the known side effect of stimulant medications. Choice A is incorrect as NP students cannot dispense medications without proper authorization. Choice B is incorrect because abruptly stopping ADHD medications can lead to withdrawal symptoms. Choice C is incorrect as crushing extended-release medications can alter their intended effect.

Correct Answer: A

Rationale: The correct answer is A: Dopamine. In Parkinson's disease, there is a loss of dopamine-producing neurons in the brain, leading to motor symptoms. Dopamine is an inhibitory neurotransmitter that plays a key role in movement control. Oxytocin (B) is a hormone involved in social bonding. Acetylcholine (C) is an excitatory neurotransmitter involved in muscle movement. Adrenaline (D) is a hormone involved in the stress response. The loss of dopamine in Parkinson's disease leads to an imbalance in neurotransmitters, causing motor dysfunction.

Correct Answer: A

Rationale: The correct answer is A: Teratogenicity. Teratogenicity refers to the ability of a drug to cause harm to a developing fetus. This factor is crucial in determining drug actions because drugs can have different effects on pregnant women and their unborn babies. Age (B), body weight (C), and metabolic rate (D) can influence drug actions, but they do not directly address the impact on a developing fetus, unlike teratogenicity. Thus, A is the correct choice as it specifically relates to the potential harm drugs can cause during pregnancy.
