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: Human papilloma virus (HPV) infection at age 32. HPV is a known risk factor for cervical cancer as it can lead to cellular changes in the cervix. Here's the rationale: 1. HPV is a sexually transmitted infection that can cause abnormal cell growth in the cervix. 2. Persistent HPV infection is a major risk factor for developing cervical cancer. 3. Age 32 is within the typical age range for HPV infection and the development of cervical cancer. 4. Choices A, B, and C are unrelated to the primary risk factor for cervical cancer, which is HPV infection.

Correct Answer: D

Rationale: The correct answer is D: To determine clients response to therapy. Evaluating BUN, creatinine, and serum electrolyte levels in a client being treated for acute pyelonephritis helps the nurse assess the effectiveness of the therapy. Changes in these levels indicate how well the kidneys are functioning and how the client is responding to treatment. Monitoring these parameters allows for adjustments in therapy if needed. Incorrect choices: A: To determine the severity of the disorder - While these tests can provide information about the severity of kidney dysfunction, the primary focus is on monitoring the response to therapy. B: To identify signs of fluid retention - While BUN and creatinine levels can indirectly indicate fluid status, the main purpose of evaluating these tests is to assess therapy response. C: To determine the location of discomfort - These tests do not provide information about the location of discomfort but rather focus on kidney function and response to treatment.

Correct Answer: C

Rationale: The correct answer is C: Glucagon. In a hypoglycemic reaction, glucagon can be administered to raise blood sugar levels quickly. Glucagon works by stimulating the liver to release stored glucose into the bloodstream. This is crucial in emergencies when oral carbohydrates are not feasible. Epinephrine (A) is used for severe allergic reactions, not hypoglycemia. 50% dextrose (B) is an oral carbohydrate used for hypoglycemia but is not always practical. Hydrocortisone (D) is a corticosteroid used for inflammatory conditions, not for hypoglycemic emergencies.

Correct Answer: B

Rationale: The correct answer is B: Protein. Antibodies are a type of protein produced by the immune system to help identify and neutralize pathogens like bacteria and viruses. Proteins are composed of amino acids, which are the building blocks of proteins. Antibodies have a specific structure that allows them to bind to specific antigens. Fat (A), Sugar (C), and Carbohydrates (D) are not primary components of antibodies and do not play a significant role in their structure or function.
