Question 1 of 5
Chemotherapeutic agents often produce a degree of myelosuppression including leukopenia. Leukopenia does not present immediately but is delayed several days or weeks because:
Correct Answer: D
Rationale: Leukopenia does not present immediately after chemotherapy because time is required to clear circulating cells before the effect on precursor cell maturation in the bone marrow becomes evident. Leukopenia is characterized by an abnormally low white blood cell count. The correct answer is D because the white cell count is not immediately affected by chemotherapy.
Choices A, B, and C are incorrect as they pertain to red blood cells (hemoglobin and hematocrit), which are not directly related to the delayed onset of leukopenia.
Question 2 of 5
A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?
Correct Answer: A
Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe.
Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.
Question 3 of 5
A female sex worker enters a clinic for treatment of a sexually transmitted disease. This disease is the most prevalent STD in the United States. The nurse can anticipate that the woman has which of the following?
Correct Answer: B
Rationale: The question describes a female sex worker seeking treatment for the most prevalent sexually transmitted disease in the United States. Chlamydia is the correct answer as it is the most common STD in the country according to epidemiological studies. While herpes (choice
A) is common, it is not the most prevalent. Gonorrhea (choice
C) and syphilis (choice
D) are less prevalent compared to chlamydia, making them incorrect choices.
Question 4 of 5
A nurse working in a pediatric clinic observes the following situations. Which of the following may indicate a delayed child to the nurse?
Correct Answer: A
Rationale: The correct answer is 'A 12-month-old that does not 'cruise''. At 12 months, a child should at least be 'cruising' (holding on to objects to walk), which is considered pre-walking. The other choices describe age-appropriate developmental milestones: sitting upright unsupported by 8 months, rolling prone to supine by 6 months, and rolling supine to prone by 3 months. Not 'cruising' at 12 months may indicate a delay in motor skills development.
Question 5 of 5
Herbal therapy has several indications for use. Primarily, herbal therapy is:
Correct Answer: A
Rationale: The correct answer is A: 'used to treat many common complaints and diseases.' Herbal therapy is commonly used to address a variety of health issues and ailments by utilizing natural remedies derived from plants.
Choices B, C, and D are incorrect because herbal therapy's primary purpose is not to promote specific diets, act as an adjunct to medications, or create specific dietary restrictions, but rather to provide alternative treatment options for various health conditions.
