1. What is levothyroxine's pharmacologic classification?

• A. Thyroid Preparations
• B. Metabolic Inhibitors
• C. Analgesic
• D. Loop Diuretic

Correct answer: A

Rationale: Levothyroxine is classified as a thyroid preparation because it is a synthetic form of the thyroid hormone thyroxine. It is primarily used to treat hypothyroidism by supplementing or replacing the natural thyroid hormones in the body, helping to regulate metabolism and energy levels. Choice B, Metabolic Inhibitors, is incorrect because levothyroxine does not inhibit metabolism but rather helps regulate it. Choice C, Analgesic, is incorrect as levothyroxine is not used for pain relief but for thyroid hormone replacement therapy. Choice D, Loop Diuretic, is also incorrect as loop diuretics are medications that act on the kidneys to increase urine production and are not related to thyroid hormone replacement therapy.

2. A healthcare provider in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings are indicative of this condition?

• A. Insidious onset of painless loss of vision
• B. Gradual reduction in peripheral vision
• C. Severe pain around the eyes
• D. Intraocular pressure of 12mm Hg

Correct answer: C

Rationale: Severe pain around the eyes that radiates over the face is a characteristic symptom of acute angle-closure glaucoma. This intense pain is typically accompanied by other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. The acute rise in intraocular pressure leads to these symptoms, indicating a medical emergency that requires immediate attention to prevent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more suggestive of conditions like age-related macular degeneration or diabetic retinopathy. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12mm Hg is within the normal range and not indicative of the acute rise seen in angle-closure glaucoma.

3. The nurse is caring for a client who has chronic angina. Treatment for the condition has been unsuccessful. Which medication does the nurse anticipate will be prescribed?

• A. Atenolol (Tenormin)
• B. Nitroglycerin (Nitrostat)
• C. Sildenafil (Viagra)
• D. Ranolazine (Ranexa)

Correct answer: D

Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.

4. A client is receiving Morphine IV for pain management. Which of the following actions should the nurse take?

• A. Monitor the client's respiratory rate every 15 minutes.
• B. Monitor the client's blood pressure every 30 minutes.
• C. Monitor the client's oxygen saturation every hour.
• D. Monitor the client's heart rate every 5 minutes.

Correct answer: A

Rationale: The correct action for the nurse is to monitor the client's respiratory rate every 15 minutes while on Morphine IV to promptly detect respiratory depression, a critical adverse effect associated with this medication. Respiratory depression is a common side effect of opioid medications like Morphine and can be life-threatening. Monitoring the respiratory rate frequently enables the nurse to identify early signs of respiratory compromise and intervene promptly. Monitoring other vital signs like blood pressure, oxygen saturation, or heart rate is important but not as crucial as monitoring respiratory rate when a client is on Morphine IV.

5. A client with brain cancer and headaches is prescribed dexamethasone. What is the purpose of this adjuvant medication?

• A. To decrease inflammation and swelling
• B. To improve concentration
• C. To induce sedation
• D. To treat depression

Correct answer: A

Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer to decrease inflammation and swelling. It helps reduce cerebral edema and relieve pressure caused by the tumor, ultimately alleviating headaches. The purpose of prescribing dexamethasone in this case is not to improve concentration (choice B), induce sedation (choice C), or treat depression (choice D). Methylphenidate, a stimulant, is used for conditions like ADHD, not for brain cancer. Hydroxyzine, an antihistamine, is primarily used for anxiety and itching, not for brain cancer. Amitriptyline, a tricyclic antidepressant, is used for conditions like depression and neuropathic pain, not specifically for brain cancer-related headaches.
