1. When teaching the guardian of a 12-year-old male client about manifestations of puberty, which of the following physical changes typically occurs first?
- A. Appearance of downy hair on the upper lip
- B. Hair growth in the axillae
- C. Enlargement of the testes and scrotum
- D. Deepening of the voice
Correct answer: C
Rationale: During puberty in males, the first physical change that typically occurs is the enlargement of the testes and scrotum. This change is due to increased production of testosterone, which stimulates growth and development of the genital organs. The appearance of downy hair on the upper lip (Choice A) and hair growth in the axillae (Choice B) usually follow the enlargement of the testes and scrotum. Deepening of the voice (Choice D) is a later stage change that occurs during puberty as the larynx (voice box) grows and the vocal cords lengthen and thicken.
2. When should the nurse plan to collect a sputum specimen for culture and sensitivity as ordered by a client's provider?
- A. In the morning upon rising.
- B. Immediately after the client eats breakfast.
- C. Before the client goes to bed.
- D. After the client has had a drink of water.
Correct answer: A
Rationale: The correct time to collect a sputum specimen for culture and sensitivity is in the morning upon rising. This timing ensures the most concentrated sample as sputum produced overnight tends to accumulate and sit in the airways, providing a quality sample for testing. Collecting the specimen immediately after eating breakfast (choice B) may introduce food particles that could contaminate the sample. Collecting it before bed (choice C) may lead to a diluted sample due to daily activities. Collecting the specimen after having a drink of water (choice D) can also result in a diluted sample, impacting the accuracy of the test results.
3. A client is receiving chemotherapy for breast cancer. Which laboratory value would be most important for the nurse to monitor?
- A. White blood cell count
- B. Hemoglobin level
- C. Serum creatinine
- D. Blood glucose level
Correct answer: A
Rationale: The correct answer is to monitor the white blood cell count. Chemotherapy can lead to neutropenia, which is a decrease in white blood cells, particularly neutrophils. Neutropenia increases the risk of infections, making it crucial to monitor the white blood cell count during chemotherapy. Monitoring hemoglobin level is important but not as critical as white blood cell count in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer, making them less relevant to monitor in this situation.
4. A client receives the influenza vaccine in a clinic. Within 15 minutes after the immunization, the client complains of itchy and watery eyes, increased anxiety, and difficulty breathing. What should be the first action in the sequence of care for this client?
- A. Maintain the airway
- B. Administer epinephrine 1:1000 as ordered
- C. Monitor for hypotension with shock
- D. Administer diphenhydramine as ordered
Correct answer: B
Rationale: In the scenario described, the client is experiencing symptoms of an anaphylactic reaction, a severe allergic response. The priority action in an anaphylactic reaction is to administer epinephrine. Epinephrine helps counteract the severe allergic response, improves breathing difficulties, and maintains airway and circulation. Administering epinephrine takes precedence to stabilize the client's condition. Options A, C, and D may be necessary in the management of anaphylaxis, but the immediate priority is to administer epinephrine to address the life-threatening symptoms.
5. A client with a diagnosis of hypertension is being assessed. Which symptom would be most concerning?
- A. Headache
- B. Blurred vision
- C. Dizziness
- D. Chest pain
Correct answer: D
Rationale: Chest pain in a client with hypertension is the most concerning symptom as it may indicate a myocardial infarction or other serious cardiac event related to hypertension. Immediate intervention is required to address potential life-threatening conditions. Headache, blurred vision, and dizziness are common symptoms associated with hypertension but are not typically indicative of an acute cardiac event requiring urgent attention.
