1. The nurse is preparing to administer the first dose of an antibiotic to a patient admitted for a urinary tract infection. Which action is most important prior to administering the antibiotic?
- A. Administering a small test dose to determine if hypersensitivity exists
- B. Having epinephrine available in case of a severe hypersensitivity reaction
- C. Monitoring baseline vital signs, including temperature and blood pressure
- D. Obtaining a specimen for culture and sensitivity
Correct answer: D
Rationale: The most crucial action before administering an antibiotic for a urinary tract infection is to obtain a specimen for culture and sensitivity. This ensures the accurate identification of the causative organism and helps determine the most effective antibiotic therapy. Administering a test dose to detect hypersensitivity is usually reserved for cases with a strong suspicion of allergy to a needed antibiotic. Keeping epinephrine available is important when there is a significant risk of a severe allergic reaction. Monitoring baseline vital signs is essential during antibiotic therapy but is not the top priority before administering the first dose.
2. A client with early breast cancer receives the results of a breast biopsy and asks the nurse to explain the meaning of staging and the type of receptors found on the cancer cells. Which explanation should the nurse provide?
- A. Lymph node involvement is not significant.
- B. Small tumors are aggressive and indicate poor prognosis.
- C. The tumor's estrogen receptor guides treatment options.
- D. Stage I indicates metastasis.
Correct answer: C
Rationale: Treatment decisions and prediction of prognosis are related to the tumor's receptor status, such as estrogen and progesterone receptor status which commonly are well-differentiated, have a lower chance of recurrence, and are receptive to hormonal therapy. Tumor staging designates tumor size and spread of breast cancer cells into axillary lymph nodes, which is one of the most important prognostic factors in early-stage breast cancer.
3. In a patient with asthma, which of the following is the most important indicator of respiratory function?
- A. Oxygen saturation.
- B. Respiratory rate.
- C. Arterial blood gases.
- D. Peak expiratory flow rate.
Correct answer: D
Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.
4. The client is preparing a morning dose of insulin, which includes 10 units of regular and 22 units of NPH. The nurse is verifying the client's preparation accuracy. What should the syringe read for the correct dose?
- A. 22 units.
- B. 10 units.
- C. 32 units.
- D. 42 units.
Correct answer: C
Rationale: The correct answer is 32 units. To determine the correct dose, the nurse needs to add the 10 units of regular insulin to the 22 units of NPH, resulting in a total of 32 units. Therefore, the syringe should read 32 units. Choices A, B, and D are incorrect because they do not reflect the accurate total dose required for the morning insulin administration.
5. Which of the following indicates a potential complication of diabetes mellitus?
- A. Inflamed and painful joints.
- B. Blood pressure of 160/100 mm Hg.
- C. Stooped posture.
- D. Hemoglobin of 9 g/dL (90 g/L).
Correct answer: B
Rationale: A blood pressure of 160/100 mm Hg indicates hypertension, which is a common complication of diabetes mellitus due to atherosclerotic changes. Hypertension is a significant risk factor for cardiovascular diseases, which are prevalent in individuals with diabetes. Inflamed and painful joints (Choice A) are not directly related to diabetes complications but may be seen in conditions like arthritis. Stooped posture (Choice C) is more indicative of musculoskeletal issues like osteoporosis, not necessarily a typical complication of diabetes. Hemoglobin level of 9 g/dL (90 g/L) (Choice D) could signify anemia, which can occur in diabetes but is not a primary complication often associated with the disease.
