Question 1 of 5
The medication that best penetrates eschar is:
Correct Answer: A
Rationale: Mafenide acetate is bacteriostatic and best penetrates eschar, making it effective for deep burn wounds. The other medications do not penetrate eschar as effectively.
Question 2 of 5
The nurse is performing an assessment on a client with a history of a tension pneumothorax. Which finding is most concerning?
Correct Answer: A
Rationale: Tracheal deviation in a tension pneumothorax indicates mediastinal shift from increased intrathoracic pressure, a life-threatening emergency requiring immediate attention.
Question 3 of 5
Which of the following is an expected finding in the assessment of a client with bulimia nervosa?
Correct Answer: C
Rationale: Bulimia nervosa involves recurrent binge eating followed by purging, often through vomiting, which exposes teeth to stomach acid, leading to enamel erosion. Extreme weight loss and lanugo are more characteristic of anorexia nervosa, and muscle wasting is not a primary feature of bulimia.
Question 4 of 5
The nurse should know that according to current thinking, the most important prognostic factor for a client with breast cancer is:
Correct Answer: B
Rationale: Although tumor size is a factor in classification of cancer growth, it is not an indicator of lymph node spread. Axillary node status is the most important indicator for predicting how far the cancer has spread. If the lymph nodes are positive for cancer cells, the prognosis is poorer. The client's previous history of cancer puts her at an increased risk for breast cancer recurrence, especially if the cancer occurred in the other breast. It does not predict prognosis, however. The estrogen-progesterone assay test is used to identify present tumors being fed from an estrogen site within the body. Some breast cancers grow rapidly as long as there is an estrogen supply such as from the ovaries. The estrogen-progesterone assay test does not indicate the prognosis.
Question 5 of 5
Nursing care for the substance abuse client experiencing alcohol withdrawal delirium includes:
Correct Answer: A
Rationale: These clients are at high risk for seizures during the 1st week after cessation of alcohol intake. Fluid intake should be increased to prevent dehydration. Environmental stimuli should be decreased to prevent precipitation of seizures. Application of restraints may cause the client to increase his or her physical activity and may eventually lead to exhaustion.
