- A. Herpes simplex keratitis
- B. Bacterial keratitis
- C. Fungal keratitis
- D. Acanthamoeba keratitis
Correct Answer: C
Rationale: The described presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is characteristic of fungal keratitis. Fungal keratitis typically presents with these specific features on clinical examination.

The nurse assists a health care provider in performing a liver biopsy. After the biopsy, the nurse should place the client in which position?
- A. Prone
- B. Supine
- C. A left side-lying position with a small pillow or folded towel under the puncture site
- D. A right side-lying position with a small pillow or folded towel under the puncture site
Correct Answer: C
Rationale: Placing the client in a left side-lying position after a liver biopsy helps to promote pressure on the puncture site, which can reduce the risk of bleeding. Placing a small pillow or folded towel under the puncture site provides additional support and helps to maintain pressure on the area. This position also helps prevent the client from putting pressure on the abdomen, which could potentially affect the biopsy site and increase the risk of bleeding or complications. Overall, positioning the client on the left side with support under the puncture site is the most appropriate and safest option after a liver biopsy.

A patient post-thyroidectomy develops signs of hypocalcemia, including tingling around the mouth and muscle cramps. Which action should the nurse take first?
- A. Administer oral calcium supplements
- B. Notify the healthcare provider
- C. Assess the patient's calcium level
- D. Encourage increased intake of dairy products
Correct Answer: C
Rationale: The first action the nurse should take when a patient post-thyroidectomy develops signs of hypocalcemia is to assess the patient's calcium level. By assessing the patient's calcium level through laboratory testing, the nurse can confirm the presence of hypocalcemia and determine the severity of the condition. This information will guide further interventions, such as administering calcium supplements or notifying the healthcare provider for additional management. It is important to confirm the diagnosis before proceeding with treatment to ensure appropriate and safe care for the patient.
A woman in active labor is receiving intravenous magnesium sulfate for the prevention of eclampsia. What maternal assessment finding indicates magnesium toxicity?
- A. Muscle weakness
- B. Increased deep tendon reflexes
- C. Hypotension
- D. Tachycardia
Correct Answer: B
Rationale: Magnesium sulfate is used to prevent eclampsia, but it can lead to toxicity if levels become too high. One common sign of magnesium toxicity is increased deep tendon reflexes, also known as hyperreflexia. This occurs because magnesium is a muscle relaxant, and elevated levels can lead to over-relaxation of muscles, causing an exaggerated reflex response. Other signs of magnesium toxicity include respiratory depression, decreased urine output, and cardiac arrest. Therefore, in a woman receiving intravenous magnesium sulfate during labor, an increase in deep tendon reflexes would indicate potential toxicity and require immediate intervention.
Which of the following should be AVOIDED by patient Sonia while she is being treated for hypothyroidism?
- A. Use of warm blankets
- B. Taking foods low in fiber
- C. Light activities done at home
- D. Exposure to cold temperature
Correct Answer: D
Rationale: Patients with hypothyroidism have a decreased ability to regulate their body temperature due to the reduced hormone levels. Exposure to cold temperatures can exacerbate this issue and lead to symptoms such as cold intolerance, feeling cold all the time, and potentially even hypothermia. It is important for patients with hypothyroidism to avoid prolonged exposure to cold temperatures to prevent any negative impact on their health.
