How do you decrease the severity and duration of pertussis infection?
- A. you don't
- B. erythromycin
- C. benzyl penicillin
- D. ampicillin
Correct Answer: A
Rationale: Pertussis antibiotics clip spread, not whooping's course; erythro, pen, cipro miss. Nurses know this chronic cough rides out.

The nurse is preparing an adolescent diagnosed with leukemia for a lumbar puncture. The nurse determines that the child understands the reason for the procedure when the child states that the procedure is done to:
- A. Make sure I don't have meningitis along with my cancer.
- B. Relieve some of the pressure on my brain.
- C. Remove the blood cancer cells so I don't have to have surgery.
- D. Check to see if the cancer has spread through my spinal cord and brain.
Correct Answer: D
Rationale: A lumbar puncture (LP) in leukemia is performed to collect cerebrospinal fluid (CSF) to check for central nervous system (CNS) involvement cancer cells spreading to the spinal cord and brain a critical staging step that influences treatment, like intrathecal chemotherapy. The adolescent's statement about checking for spread reflects accurate understanding, essential for informed consent and reducing anxiety through clarity. Ruling out meningitis is a possible LP use, but in leukemia, CNS metastasis is the primary concern unless symptoms suggest infection. Relieving brain pressure applies to conditions like hydrocephalus, not leukemia's typical presentation. Removing cancer cells via LP isn't a treatment; it's diagnostic. The nurse's confirmation of this understanding ensures the child is prepared, aligning with pediatric oncology's emphasis on patient education and procedural readiness.
All of the following are potential factors leading to weight gain EXCEPT:
- A. Disrupted circadian rhythm
- B. Use of anti-histamines and sulphonylureas
- C. Changes in gut microbiota
- D. Controlled food portions that are of low energy density
Correct Answer: D
Rationale: Weight gain factors include disrupted circadian rhythm (metabolic dysregulation), antihistamines/sulphonylureas (appetite increase, insulin secretion), and gut microbiota shifts (altered energy harvest). Controlled food portions of low energy density (e.g., vegetables) reduce calorie intake, aiding weight loss, not gain, per obesity research. This exception highlights dietary control's role in managing chronic conditions like diabetes or obesity, guiding physicians in patient counseling for sustainable weight regulation.
People with metabolic syndrome have an increased risk of which of the following disorders, besides type 2 diabetes mellitus?
- A. Hypertension, infections
- B. Myocardial infarction, hypertension
- C. Myocardial infarction, infections
- D. Myocardial infarction, liver cirrhosis
Correct Answer: B
Rationale: Metabolic syndrome hikes heart attacks, hypertension vascular hits, not infections or cirrhosis extras. Nurses track this, a chronic CV duo.
Spirometry is used to determine the severity of COPD and to monitor disease progression. This test measures
- A. The ratio of volume of air the patient can forcibly exhale in 1 second and forced vital capacity.
- B. The ratio of residual volume when patient has fully exhaled and forced vital capacity.
- C. The ratio of forced vital capacity and volume of air the patient can forcibly exhale in 6 seconds.
- D. The ratio of respiratory effort and respiratory rate.
Correct Answer: A
Rationale: Spirometry is the gold standard for COPD diagnosis and staging, measuring airflow obstruction. The ratio of forced expiratory volume in 1 second (FEVâ‚) to forced vital capacity (FVC) FEVâ‚/FVC quantifies limitation; a value <0.7 post-bronchodilator confirms COPD, with FEVâ‚ percentage grading severity (e.g., GOLD stages). Residual volume (RV) to FVC isn't standard in basic spirometry RV requires advanced testing (e.g., plethysmography) and reflects air trapping, not routine staging. FVC versus a 6-second exhale (FEV₆) approximates in some settings but isn't the clinical norm for COPD. Respiratory effort and rate aren't spirometric; they're observational. FEVâ‚/FVC's precision, per Deravin and Anderson (2019), tracks obstruction progression and guides therapy, making it foundational for assessing COPD's irreversible nature.
A client tells the oncology nurse about an upcoming vacation to the beach to celebrate completing radiation treatments for cancer. What response by the nurse is most appropriate?
- A. Avoid getting salt water on the radiation site.
- B. Do not expose the radiation area to direct sunlight.
- C. Have a wonderful time and enjoy your vacation!
- D. Remember you should not drink alcohol for a year.
Correct Answer: B
Rationale: Post-radiation skin at the treatment site remains highly sensitive to ultraviolet (UV) rays due to damage to the epidermal layer, increasing the risk of burns, irritation, or delayed healing. The nurse's most appropriate response is to advise against exposing the radiation area to direct sunlight, a precaution that persists for at least a year after treatment to protect skin integrity. Avoiding saltwater isn't a standard concern unless the skin is broken, which isn't indicated here. Simply wishing the client well ignores the teaching opportunity and potential risk. The alcohol restriction isn't a universal post-radiation rule unless tied to specific treatments or conditions not mentioned. Educating about sun exposure empowers the client to enjoy the vacation safely, aligning with nursing's preventive care focus and ensuring the celebration isn't marred by avoidable complications.
