Which of the ff is the effect of a decrease in the number of lymphocytes with age?
- A. Decreased resistance to infection
- B. Cognitive problems
- C. Urinary incontinence
- D. Decrease in various blood components
Correct Answer: A
Rationale: Lymphocytes are a type of white blood cell that plays a crucial role in the body's immune system by helping to fight off infections and diseases. A decrease in the number of lymphocytes with age means that the immune system may not function as effectively as it used to. This can lead to a decreased resistance to infections, making older individuals more susceptible to illnesses and diseases. Therefore, the effect of a decrease in the number of lymphocytes with age is a decreased resistance to infection.

- A. Weigh the client.
- B. Administer oral hydrocortisone.
- C. Test urine for ketones.
- D. Assess vital signs.

Addisonian crisis is a life-threatening condition resulting from acute adrenal insufficiency. Monitoring vital signs such as blood pressure, heart rate, respiratory rate, and temperature can provide valuable information about the client's condition and response to treatment. Changes in vital signs may indicate worsening or improvement in the client's health status, helping the nurse to make timely interventions and adjustments in the client's care plan. Regular assessment of vital signs is essential in managing the client's stability and preventing complications during this critical period.

It is primarily caused by the human papillomavirus (HPV), a sexually transmitted infection. Regular Pap smears can help detect precancerous changes in the cervix early, making it a preventable and treatable cancer if caught early. It is important for nurses to educate their clients on the importance of routine screenings and HPV vaccination to prevent cervical cancer.
Which of the ff. nursing actions prepares a patient for a lumbar puncture?
- A. Administering enemas until clear
- B. Positioning the patient on his or her side

Correct Answer: B
Rationale: Positioning the patient on their side is a critical nursing action that prepares a patient for a lumbar puncture. This position is usually used during the procedure to allow easier access to the lumbar region. Placing the patient on their side helps provide better visualization of the spinal landmarks and facilitates the correct positioning of the needle for the lumbar puncture. This position also helps minimize the risk of complications and ensures the safety and comfort of the patient during the procedure. Administering enemas until clear, removing all metal jewelry, and removing the patient's dentures are not specifically associated with preparing a patient for a lumbar puncture.
The nurse is preparing an in-service education to staff about atraumatic care for pediatric patients. Which intervention should the nurse include?
- A. Prepare the child for separation from parents during hospitalization by reviewing a video.
- B. Prepare the child before any unfamiliar treatment or procedure by demonstrating on a stuffed animal.
- C. Help the child accept the loss of control associated with hospitalization.
- D. Help the child accept pain that is connected with a treatment or procedure.
Correct Answer: B
Rationale: Atraumatic care for pediatric patients aims to minimize emotional and psychological distress during hospitalization or medical procedures. Option B, preparing the child before any unfamiliar treatment or procedure by demonstrating it on a stuffed animal, is an appropriate intervention. This technique allows the child to understand what will happen, reduces fear of the unknown, and promotes a sense of control. By using a stuffed animal as a teaching tool, the nurse can provide clear information to the child in a non-threatening way, helping to alleviate anxiety and stress. This intervention encourages trust between the child and healthcare provider and promotes a positive healthcare experience for the pediatric patient.
