Nokea
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 described presentation is classic for acute angle-closure glaucoma. This condition is characterized by sudden-onset severe eye pain, headache, nausea, and vomiting. The red eye, steamy cornea (corneal edema), and mid-dilated non-reactive pupil are consistent with acute angle-closure glaucoma. The sudden increase in intraocular pressure leads to impaired aqueous humor outflow, causing these symptoms. Immediate intervention is required to prevent permanent vision loss in such cases. Central retinal artery occlusion would present with sudden painless vision loss. Optic neuritis typically presents with vision loss and pain with eye movements. Corneal ulcer presents with eye discomfort, foreign body sensation, and may have a history of corneal trauma or contact lens wear.

A patient in the ICU develops acute gastrointestinal bleeding (GIB) requiring urgent intervention. What intervention should the healthcare team prioritize to manage the patient's bleeding?
- A. Perform endoscopic hemostasis with mechanical or thermal techniques.
- B. Administer proton pump inhibitors (PPIs) to reduce gastric acid secretion.
- C. Implement strict bed rest to minimize physical exertion and bleeding risk.
- D. Recommend transfusion of fresh frozen plasma to correct coagulopathy.
Correct Answer: A
Rationale: The healthcare team should prioritize performing endoscopic hemostasis with mechanical or thermal techniques in a patient with acute gastrointestinal bleeding (GIB) requiring urgent intervention. This approach involves directly visualizing the bleeding site and applying methods such as clipping, coagulation, or band ligation to stop the bleeding. Endoscopic hemostasis is considered the gold standard for managing acute GIB as it allows for both diagnostic and therapeutic intervention in real-time, offering a targeted and effective way to control bleeding and prevent recurrent episodes. Administering proton pump inhibitors (PPIs) may help in reducing gastric acid secretion and promoting ulcer healing but is not the primary intervention for actively bleeding patients. Implementing strict bed rest may be necessary in some cases to minimize physical exertion, but it is not the primary intervention to manage acute GIB. Transfusion of fresh frozen plasma to correct coagulopathy may be necessary if
A nurse is preparing to perform an intracranial pressure (ICP) monitoring procedure for a patient with traumatic brain injury. What action should the nurse prioritize to ensure procedural accuracy?
- A. Ensuring proper zeroing and calibration of the ICP monitoring system
- B. Positioning the patient in a high-Fowler's position during the procedure
- C. Administering prophylactic antibiotics to prevent infection
- D. Placing the ICP monitor in the subarachnoid space via lumbar puncture
Correct Answer: A
Rationale: The nurse should prioritize ensuring proper zeroing and calibration of the ICP monitoring system to ensure procedural accuracy and reliability of the measurements obtained. Proper zeroing involves setting the transducer at the level of the patient's external auditory meatus (ear), which serves as a reference point for accurate ICP readings. Calibration is necessary to establish accurate pressure measurements. Incorrect zeroing or calibration can lead to inaccurate ICP readings, which can impact clinical decision-making for patients with traumatic brain injury. Positioning the patient in a high-Fowler's position, administering prophylactic antibiotics, or placing the ICP monitor in the subarachnoid space via lumbar puncture are not directly related to ensuring the accuracy of the ICP monitoring procedure.
Which of the following interventions is recommended for managing a patient with a suspected opioid overdose?
- A. Administering naloxone intravenously.
- B. Providing respiratory support with bag-valve-mask ventilation.
- C. Encouraging the patient to drink fluids rapidly.
- D. Administering benzodiazepines for sedation.
Correct Answer: A
Rationale: Naloxone is a medication used to reverse the effects of an opioid overdose by binding to opioid receptors and displacing the opioids. Administering naloxone intravenously is the recommended intervention for managing a patient with a suspected opioid overdose as it can quickly reverse respiratory depression, sedation, and other effects of opioids. This intervention can be life-saving in cases of opioid overdose and is a critical step in the management of such patients. Providing respiratory support with bag-valve-mask ventilation may be necessary in addition to naloxone administration to ensure adequate oxygenation, but naloxone remains the primary intervention to reverse the effects of opioids. Encouraging the patient to drink fluids rapidly or administering benzodiazepines for sedation are not recommended interventions for managing a suspected opioid overdose.
A postpartum client who delivered a macrosomic infant expresses concerns about breastfeeding difficulties due to the baby's size. What nursing intervention should be prioritized to support successful breastfeeding in this situation?
- 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: Providing education on techniques to improve latch and milk transfer should be prioritized to support successful breastfeeding in this situation. Newborns who are macrosomic (large for gestational age) may have difficulties latching due to their size and may require additional support to effectively breastfeed. By educating the postpartum client on proper latch techniques and milk transfer, the nurse can help optimize the breastfeeding experience for both the mother and baby. This intervention focuses on addressing the specific concerns related to the infant's size and aims to promote successful breastfeeding despite potential challenges. As such, recommending supplemental formula feedings, encouraging the client to avoid breastfeeding, or immediately referring to a lactation consultant may not directly address the immediate need for support in improving breastfeeding in this situation.
This theory categorizes professionals as Novice to experts is by ______.
- A. Benner
- B. Pender
- C. Abdellah
- D. Kings
Correct Answer: A
Rationale: The theory that categorizes professionals as Novice to experts is by Patricia Benner. Patricia Benner developed the Novice to Expert model, which describes how individuals progress through five levels of proficiency in a skill or field. The five levels are Novice, Advanced Beginner, Competent, Proficient, and Expert. Benner's model is widely used in nursing education and research to understand how nurses develop their clinical skills and expertise over time.
