A patient presents with sudden-onset, severe eye pain, headache, nausea, and vomiting. On examination, the affected eye appears red, with a steamy cornea and mid-dilated, non-reactive pupil. Which of the following conditions is most likely responsible for this presentation?
- A. Acute angle-closure glaucoma
- B. Central retinal artery occlusion
- C. Optic neuritis
- D. Corneal ulcer
Correct Answer: A
Rationale: The clinical presentation described is highly suggestive of acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. The red eye, steamy cornea (due to corneal edema), and mid-dilated, non-reactive pupil (from the unopposed force of the dilator muscle) are classic findings in acute angle-closure glaucoma. The increase in intraocular pressure compromises blood flow to the eye, leading to symptoms of blurred vision and possible visual loss. Immediate management usually involves lowering intraocular pressure with medications or surgical intervention to prevent vision loss. Central retinal artery occlusion, optic neuritis, and corneal ulcer typically present with different clinical features and are not consistent with the described presentation.

A woman in active labor experiences persistent fetal malposition, with the fetus in a transverse lie presentation. What nursing intervention should be prioritized to address this abnormal labor presentation?
- A. Facilitating external cephalic version (ECV)
- B. Assisting the mother into a hands-and-knees position
- C. Preparing for immediate instrumental delivery
- D. Initiating continuous electronic fetal monitoring
Correct Answer: B
Rationale: When a woman in active labor experiences persistent fetal malposition, such as a transverse lie presentation, assisting the mother into a hands-and-knees position is a nursing intervention to prioritize. This position can help encourage the fetus to rotate into a more favorable position for delivery, such as a head-down position. By placing the mother in a hands-and-knees position, gravity can assist in shifting the fetus to the correct position. This intervention is non-invasive and can be effective in promoting the progress of labor and avoiding the need for more invasive interventions like instrumental delivery or cesarean section. However, if the fetus does not rotate or if there are signs of fetal distress, further interventions may be necessary.
A patient with a history of chronic obstructive pulmonary disease (COPD) is experiencing respiratory distress. Which nursing intervention is the priority for managing the patient's respiratory status?
- A. Administering bronchodilators
- B. Positioning the patient in high Fowler's position
- C. Performing chest physiotherapy
- D. Administering oxygen therapy
Correct Answer: D
Rationale: Administering oxygen therapy is the priority nursing intervention for managing a patient with COPD experiencing respiratory distress. In COPD, the patient's lungs are less efficient at oxygen exchange, leading to hypoxemia. Oxygen therapy helps improve oxygenation in the body and alleviates respiratory distress in these patients. Positioning the patient in high Fowler's position can also help improve lung expansion, but providing supplemental oxygen takes precedence in addressing the underlying hypoxemia. Administering bronchodilators and performing chest physiotherapy aim to manage airway obstruction and promote airway clearance, but ensuring the patient has adequate oxygenation is crucial in the immediate management of respiratory distress in COPD.
A patient presents with generalized weakness, headache, and difficulty concentrating. Laboratory tests reveal normocytic normochromic anemia, normal iron studies, and elevated serum erythropoietin levels. Which of the following conditions is most likely to cause these findings?
- A. Chronic kidney disease (CKD)
- B. Iron deficiency anemia
- C. Thalassemia
- D. Aplastic anemia
Correct Answer: A
Rationale: The patient in this scenario presents with normocytic normochromic anemia, normal iron studies, and elevated serum erythropoietin levels. These findings are characteristic of anemia of chronic disease, which is commonly seen in patients with chronic kidney disease (CKD). In CKD, there is a decrease in renal production of erythropoietin, leading to reduced stimulation of erythropoiesis and subsequent anemia. The normocytic normochromic anemia pattern is typical in anemia of chronic disease, as opposed to microcytic hypochromic anemia seen in iron deficiency anemia and thalassemia. Aplastic anemia is characterized by pancytopenia, which is not described in the scenario. Therefore, the most likely cause of the patient's presentation is chronic kidney disease.
A patient in the ICU develops acute kidney injury (AKI) secondary to hypovolemic shock. What intervention should the healthcare team prioritize to manage the patient's renal function?
- A. Administer intravenous fluids to restore circulating volume.
- B. Initiate continuous renal replacement therapy (CRRT) for RRT.
- C. Implement strict dietary restrictions to reduce renal workload.
- D. Recommend nephrotoxic medications for therapeutic purposes.
Correct Answer: A
Rationale: In a patient with acute kidney injury (AKI) secondary to hypovolemic shock, the priority intervention to manage the patient's renal function is to administer intravenous fluids to restore circulating volume. Hypovolemic shock leads to decreased blood flow to the kidneys, resulting in hypoperfusion and ischemic damage to the renal tubules. Prompt correction of hypovolemia with intravenous fluids helps improve renal perfusion and function by increasing blood flow to the kidneys. Adequate fluid resuscitation can potentially prevent further kidney damage and support kidney function recovery. It is crucial to address the underlying cause of AKI (hypovolemia in this case) to prevent complications and improve patient outcomes. Initiating renal replacement therapy or recommending nephrotoxic medications would not be the initial interventions for managing AKI in this scenario.
A postpartum client who delivered via cesarean section expresses concerns about breastfeeding difficulties and worries about insufficient milk supply. What nursing intervention should be prioritized to address the client's concerns?
- A. Providing education on techniques to improve latch and milk transfer
- B. Recommending supplemental formula feedings to ensure adequate nutrition
- C. Encouraging the client to avoid breastfeeding to prevent discomfort
- D. Referring the client to a lactation consultant for specialized support
Correct Answer: A
Rationale: The correct nursing intervention to prioritize in this situation is providing education on techniques to improve latch and milk transfer. Cesarean section deliveries can sometimes pose challenges for breastfeeding initiation, but with proper education and support, many women can successfully breastfeed following a C-section. By teaching the client techniques to improve latch and milk transfer, the nurse can help address the client's concerns about breastfeeding difficulties and worries about insufficient milk supply. This proactive approach empowers the client to overcome breastfeeding challenges and increase their confidence in their ability to breastfeed successfully. Referring the client to a lactation consultant for specialized support may also be beneficial, but providing initial education on latch and milk transfer is crucial in this early postpartum period. Recommending formula feedings or discouraging breastfeeding may not be appropriate interventions, as they can affect the establishment of breastfeeding and undermine the client's breastfeeding goals.
