Question 1 of 5
Which of the following procedures is necessary to establish a definitive diagnosis of breast cancer?
Correct Answer: D
Rationale: Diaphanography, also known as transillumination, is a painless, noninvasive imaging technique that involves shining a light source through the breast tissue to visualize the interior. It must be used in conjunction with a mammogram and physical examination. Mammography is a useful tool for screening but is not considered a means of diagnosing breast cancers. Thermography is a pictorial representation of heat patterns on the surface of the breast. Breast cancers appear as a 'hot spot' owing to their higher metabolic rate. Biopsy either by needle aspiration or by surgical incision is the primary diagnostic technique for confirming the presence of cancer cells.
Question 2 of 5
The physician has ordered DDAVP (desmopressin acetate) for a client with diabetes insipidus. Which finding indicates that the medication is having its intended effect?
Correct Answer: C
Rationale: DDAVP reduces excessive urination in diabetes insipidus by mimicking antidiuretic hormone, decreasing urinary output. Appetite, blood sugar, and activity are not directly affected.
Question 3 of 5
The nurse is caring for a client with a chest tube. Which observation requires immediate intervention?
Correct Answer: D
Rationale: Lying on the affected side can compress the chest tube, obstructing drainage and risking pneumothorax or tension pneumothorax, requiring immediate repositioning. Continuous bubbling in the water seal is expected initially, and the other findings are appropriate.
Question 4 of 5
Which early morning activity helps to reduce the symptoms associated with rheumatoid arthritis?
Correct Answer: C
Rationale: Holding a warm cup of coffee can reduce morning stiffness in rheumatoid arthritis by providing warmth and encouraging gentle hand movement. The other activities do not specifically alleviate joint stiffness.
Question 5 of 5
A pregnant client continues to visit the clinic regularly during her pregnancy. During one of her visits while lying supine on the examining table, she tells the RN that she is becoming light-headed. The RN notices that the client has pallor in her face and is perspiring profusely. The first intervention the RN should initiate is to:
Correct Answer: D
Rationale: This position would cause the gravid uterus to bear the increased pressure of the vena cava, which could lead to maternal hypotension, in turn causing the client to continue to have pallor and to feel light-headed. This would not be the first intervention the RN should initiate. The RN should understand the supine position and its effect on the gravid uterus and vena cava. The RN's first intervention should be one that helps to alleviate the client's symptoms. Obtaining her vital signs will not alleviate her symptoms. This would move the gravid uterus off of the client's vena cava, which would alleviate the maternal hypotension that is the cause of her symptoms.
