Adult Health Nursing Test Banks

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.

Correct Answer: B

Rationale: The positive practice environment (PPE) in a health care setting typically includes components such as waste management, infection control, and peer review. However, electrical wires are not a standard component of the PPE in a work setting. Electrical safety is important in a healthcare facility, but it is usually addressed in a separate set of guidelines and protocols focusing specifically on electrical safety and maintenance. Therefore, among the given options, electrical wires are not considered a component of the positive practice environment in the work setting.

Correct Answer: B

Rationale: When a nurse is delegating tasks to a nursing assistant, the principle that should guide the nurse's delegation decisions is assigning tasks based on the assistant's level of experience (Option B). It is essential to take into consideration the skills, competencies, and experience level of the nursing assistant to ensure that the tasks delegated are suitable for them to perform safely and effectively. Delegating tasks beyond the assistant's level of experience may result in errors, inefficiencies, or compromised patient care. Therefore, matching tasks with the assistant's experience level is crucial in successful delegation and providing quality patient care.

Correct Answer: B

Rationale: When a patient with a suspected spinal injury is found unconscious, the priority action is to secure the airway without jeopardizing the cervical spine. A jaw thrust maneuver is the appropriate technique to open the airway in this situation because it allows for the maintenance of neutral alignment of the cervical spine while ensuring proper ventilation. Moving the patient to a flat surface or applying a cervical collar could potentially worsen the spinal injury if not done correctly, and checking for responsiveness should only be done after ensuring a patent airway. Therefore, the safest and most effective initial action is to perform a jaw thrust maneuver to establish a clear airway.

Correct Answer: A

Rationale: Von Willebrand disease is a hereditary bleeding disorder that results from a deficiency or dysfunction of von Willebrand factor (vWF), a protein that plays a key role in platelet adhesion and the initiation of primary hemostasis. The clinical manifestations of von Willebrand disease include recurrent mucocutaneous bleeding, such as nosebleeds, easy bruising, and gum bleeding. Laboratory findings typically show a prolonged bleeding time due to impaired platelet function, while platelet count, PT (prothrombin time), and aPTT (activated partial thromboplastin time) are usually normal. This distinguishes von Willebrand disease from other bleeding disorders such as hemophilia A (Factor VIII deficiency), which would show abnormal PT and aPTT due to deficiencies in specific clotting factors. Thrombocytopenia, on the other hand, would be characterized by a low platelet count
