why might breast implants interfere with mammography

Nclex Exam Cram Practice Questions

1. Why might breast implants interfere with mammography?

A. They might cause additional discomfort.
B. They are contraindications to mammography.
C. They are likely to be dislodged.
D. They might prevent detection of masses.

Correct answer: D

Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.

2. When providing perineal care to a female client, how should the nurse perform the procedure?

A. with gloves, washing the perineal area from front to back
B. without gloves, having the client perform all care
C. with gloves, washing the perineal area from back to front
D. without gloves, pouring water from a sterile bottle

Correct answer: A

Rationale: When providing perineal care to a female client, the nurse should wear gloves and wash the perineal area from front to back. This technique helps prevent the introduction of E. coli and other bacteria into the urethra, reducing the risk of urinary tract infections. Washing from back to front can introduce bacteria from the anal area to the urethra, leading to infections. Performing the procedure without gloves or having the client perform all care does not adhere to infection control practices. Pouring water from a sterile bottle alone may not ensure proper cleansing and infection prevention. Therefore, choices B, C, and D are incorrect as they do not follow proper perineal care guidelines.

3. Which of the following is not an indication for pelvic ultrasonography?

A. to measure uterine size
B. to detect multiple pregnancies
C. to measure renal size
D. to detect foreign bodies

Correct answer: C

Rationale: Pelvic ultrasonography is commonly used to assess various conditions. Choices A, B, and D are all valid reasons for performing pelvic ultrasonography. Measuring uterine size helps evaluate conditions like fibroids, while detecting multiple pregnancies is essential for prenatal care. Furthermore, identifying foreign bodies can aid in diagnosing certain conditions. However, assessing renal size is typically not a primary reason for pelvic ultrasonography, making choice C the correct answer.

4. Which of the following is not a function of parathyroid hormone?

A. moving calcium from bones to the bloodstream
B. inhibiting renal tubular reabsorption of phosphorus
C. promoting renal tubular reabsorption of calcium
D. enhancing renal production of vitamin D metabolites

Correct answer: B

Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

5. A case manager is reviewing the records of the clients in the nursing unit. Which note(s) in a client's record indicate an unexpected outcome and the need for follow-up?

A. A client is performing their own colostomy irrigations.
B. A client with a central venous catheter has a temperature of 100.6°F.
C. A client who has just undergone surgery has a urine output of more than 30 mL/hr.
D. A client with a new diagnosis of diabetes mellitus is self-administering insulin.

Correct answer: B

Rationale: A case manager is a healthcare professional responsible for coordinating a client's care from admission through and after discharge. They evaluate and update the plan of care as needed, monitoring for unexpected outcomes and providing follow-up. A temperature of 100.6°F in a client with a central venous catheter is an unexpected outcome that requires follow-up due to the potential indication of an infection. Choices A, C, and D describe expected outcomes and appropriate self-care management. The client self-irrigating their colostomy, a post-surgical client having adequate urine output, and a newly diagnosed diabetic self-administering insulin are all positive indicators of self-care and expected outcomes, not requiring immediate follow-up.
