The nurse is preparing a client for magnetic resonance imaging (MRI) to confirm or rule out a spinal cord lesion. During the MRI scan, which of the following would pose a threat to the client?

Correct Answer: B

Rationale: The correct answer is B: The client wears a watch and wedding band. This is because metal objects such as watches and jewelry can be hazardous during an MRI scan due to the strong magnetic field, leading to potential movement or heating of the metal objects, causing harm to the client. A: The client lies still - This is important for obtaining clear images during an MRI scan and does not pose a threat to the client. C: The client asks questions - Asking questions during an MRI scan does not pose a direct threat to the client's safety. D: The client hears thumping sounds - Thumping sounds are a normal part of the MRI scan and do not pose a threat to the client's safety.

Correct Answer: D

Rationale: The correct answer is D: Administer pain medication. The priority in this situation is to address the patient's pain and provide relief. Administering pain medication will help alleviate the discomfort and enable the patient to mobilize with crutches or a walker. Walking without pain is crucial for the patient's recovery. Explanation for other choices: A: Assisting the patient to walk with crutches may worsen the pain and should not be attempted until the pain is managed. B: Obtaining a walker is not the priority as the immediate concern is addressing the patient's pain. C: Consulting physical therapy may be beneficial in the long term, but immediate pain relief is the priority in this situation.

Correct Answer: C

Rationale: The correct answer is C: Perform a thorough nursing health history. This method is the best for gathering information about a patient's habits and lifestyle patterns because it involves asking specific questions related to the patient's daily routines, habits, and lifestyle choices. By obtaining a comprehensive health history, the nurse can gather valuable information about the patient's diet, exercise habits, sleep patterns, stress levels, substance use, and other lifestyle factors that may impact their health. Reviewing lab results (A) may provide some information but not specifically about habits and lifestyle. Conducting a physical assessment (B) focuses more on the patient's physical condition rather than lifestyle. Prolonging the termination phase of the interview (D) is not a method of data collection and does not focus on gathering information about habits and lifestyle patterns.

Correct Answer: A

Rationale: The correct answer is A: Vision changes. This is crucial to report immediately because tamoxifen can cause serious eye problems such as retinopathy. Vision changes could indicate a potentially serious adverse reaction that requires prompt medical attention to prevent permanent damage. Headache, hearing loss, and anorexia are not typically associated with tamoxifen use and are less urgent in nature. Reporting vision changes promptly can help prevent irreversible harm and ensure timely intervention.

Correct Answer: D

Rationale: The correct answer is D, as exercise and a weight reduction diet are essential components in managing type 2 diabetes. Exercise helps lower blood glucose levels and improves insulin sensitivity. Weight reduction reduces insulin resistance. Choice A is incorrect because maintaining blood glucose levels between 180-200mg/dl is too high and can lead to complications. Choice B is incorrect as complete smoking cessation is crucial for overall health and diabetes management. Choice C is incorrect because eye examinations should be done annually, not every 2 years, to monitor for diabetic retinopathy. In summary, choice D is the best option as it directly addresses the management of type 2 diabetes.

Correct Answer: C

Rationale: The correct answer is C: Bone marrow. Blood cells are primarily formed in the bone marrow through a process called hematopoiesis. The bone marrow contains stem cells that differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. Arterioles are small blood vessels that carry blood away from the heart, not involved in blood cell formation. Lymphoid tissue plays a role in immune function but not in blood cell production. Muscle tissue is primarily responsible for movement and does not have a role in blood cell formation. Therefore, the bone marrow is the correct answer as it is the main site of blood cell production in the body.

Correct Answer: A

Rationale: The correct answer is A: abdominal pain related to decreased peristalsis. Ulcerative colitis causes inflammation and ulcers in the colon, leading to abdominal pain due to decreased peristalsis. This impairs the movement of stool through the colon, resulting in pain. Choice B is incorrect as diarrhea is a common symptom of ulcerative colitis, not hyperosmolar intestinal contents. Choice C is incorrect as ulcerative colitis often leads to diarrhea and not fluid volume excess. Choice D is incorrect as activity intolerance is not directly related to ulcerative colitis, whereas abdominal pain is a common symptom associated with the condition.

Correct Answer: C

Rationale: The most pertinent nursing diagnosis for the patient with a right femur fracture stabilized in a full leg cast is "Acute pain" (Choice C). The rationale for this is as follows: 1. The patient is experiencing moderate discomfort due to the fracture and immobilization in the cast, indicating a need for pain management. 2. Acute pain is a priority in this situation as it can impact the patient's comfort, mobility, and overall recovery. 3. Managing pain effectively is crucial for promoting healing, preventing complications, and improving the patient's quality of life. 4. Posttrauma syndrome (Choice A) may be a consideration in the long term but is not the immediate priority. Constipation (Choice B) is not the most pertinent nursing diagnosis in this scenario. Anxiety (Choice D) may be present but addressing pain is more urgent and directly related to the patient's current condition.

Correct Answer: B

Rationale: The correct answer is B: Focused assessment. In this scenario, the nurse is continuously monitoring specific aspects such as vital signs, pupils, and orientation at regular intervals, which is characteristic of a focused assessment. This type of assessment allows the nurse to gather specific data related to the client's condition and respond promptly to any changes. A: Initial assessment is conducted upon admission to establish baseline data. C: Time-lapsed reassessment involves comparing current data to previous assessments over a longer period. D: Emergency assessment is performed in urgent situations to quickly identify life-threatening issues. By systematically assessing the client's vital signs, pupils, and orientation at frequent intervals, the nurse can provide timely and appropriate care in the intensive care unit setting.
