The attending physician ordered a Magnetic Resonance Imaging (MRI) to patient Sarah in order to validate the medical impression. This imaging technique is done to detect _________.

Correct Answer: A

Rationale: Magnetic Resonance Imaging (MRI) is a specialized medical imaging technique that uses magnetic fields and radio waves to create detailed images of the organs and tissues within the body. In the context of the scenario provided, an MRI is ordered by the attending physician to validate the medical impression.

Correct Answer: D

Rationale: Restlessness caused by pain often manifests as increased perspiration and constant change of position. When a person is in pain, they may become sweaty or clammy due to increased sympathetic nervous system activity. Additionally, they may constantly shift or fidget in an attempt to find a more comfortable position that can alleviate the pain they are experiencing. Therefore, it is crucial for Nurse Chona to accurately document these behaviors as signs of pain-related restlessness. Difficulty of breathing (Option A), increased respiratory rate and blood pressure (Option B), and increased heart rate (Option C) are more indicative of hypoxia or respiratory distress rather than pain-related restlessness.

Correct Answer: B

Rationale: The symptoms described in the patient, such as tremors, rigidity, bradykinesia (slow movement), and postural instability, along with the presence of a shuffling gait, stooped posture, and masked facies, are classic features of Parkinson's disease. These motor symptoms are primarily caused by the degeneration of dopamine-producing neurons in the substantia nigra region of the brain. This results in an imbalance of neurotransmitters, particularly dopamine, leading to motor dysfunction and characteristic movement abnormalities seen in Parkinson's disease.

Correct Answer: B

Rationale: The priority nursing diagnosis for a patient undergoing surgery (closure of the sac) would be risk for infection. This is because surgical procedures increase the risk of infection due to the breach in the skin and introduction of microorganisms. Infection can lead to serious complications, delay healing, and prolong recovery time. Therefore, prevention, early detection, and prompt treatment of infections are essential in the perioperative period to ensure the best possible outcomes for the patient.

Correct Answer: B

Rationale: Attending a lecture-demonstration on doing first aid is essential for the growth of a student nurse as it equips them with crucial knowledge and skills to respond effectively in emergency situations. First aid training teaches basic life-saving techniques and how to provide immediate care until medical professionals arrive. This knowledge is vital in the healthcare field, allowing the student nurse to provide immediate assistance and potentially save lives. By learning first aid procedures, the student nurse can enhance their skills, confidence, and overall capability to care for patients in various settings. This continuous learning and improvement are key to personal growth and professional development in the healthcare industry.

Correct Answer: C

Rationale: Feces, urine, blood, and other body fluids are considered as vehicles of transmission in the context of communicable diseases. These substances can carry and transmit disease-causing microorganisms such as bacteria, viruses, and parasites from infected individuals to others. Through close contact or exposure to these contaminated body fluids, the pathogens can enter the body of another person and cause infection. Nurses like Nurse Keena must exercise caution and use appropriate infection control measures to prevent transmission of communicable diseases through these vehicles.

Correct Answer: A

Rationale: Acute narrow-angle glaucoma is a medical emergency that requires timely intervention to reduce intraocular pressure. Acetazolamide (Diamox) is a medication commonly used to treat this condition as it works as a carbonic anhydrase inhibitor, reducing the production of aqueous humor in the eye. By reducing the production of aqueous humor, acetazolamide helps decrease intraocular pressure rapidly, which is crucial in managing acute narrow-angle glaucoma. Other options listed, such as Furosemide (Lasix), Atropine, and Urokinase (Abbokinase), are not typically used in the treatment of acute narrow-angle glaucoma.

Correct Answer: C

Rationale: The most appropriate intervention for a patient with end-stage dementia experiencing agitation and restlessness is to create a calm and soothing environment to promote relaxation. Patients with dementia often respond positively to a familiar and tranquil setting, which can help reduce their symptoms of agitation and restlessness. This approach is preferred over administering antipsychotic medications or recommending physical exercise, as these may not be feasible or beneficial for patients in the advanced stages of dementia. Referring the patient to a psychiatrist may not address the immediate need for symptom management and can be considered if other interventions are ineffective. Creating a calm environment, such as dim lighting, soft music, and familiar objects, can help provide comfort and reduce distress for the patient.

Correct Answer: C

Rationale: Mastitis is an infection of the breast tissue that may occur in postpartum clients. When a postpartum client exhibits signs of mastitis, including breast tenderness, erythema, and warmth, it is crucial to notify the healthcare provider immediately. Prompt medical evaluation is necessary to determine the appropriate treatment plan, which may include antibiotics. Delay in treatment can lead to complications, such as abscess formation. Encouraging the client to continue breastfeeding and applying warm compresses may provide some relief but do not address the underlying infection. Administering oral antibiotics would require a prescription from the healthcare provider, hence notifying the provider is the most appropriate initial nursing action in this situation.
