Which is descriptive of bulimia during adolescence?
- A. Strong sense of control over eating behavior
- B. Feelings of elation after the binge-purge cycle
- C. Profound lack of awareness that the eating pattern is abnormal
- D. Weight that can be normal, slightly above normal, or below normal
Correct Answer: C
Rationale: During adolescence, individuals with bulimia often have a profound lack of awareness that their eating pattern is abnormal. This lack of awareness can be attributed to various factors, such as societal pressures, distorted body image, and the normalization of disordered eating behaviors within their social circle. Adolescents with bulimia may not recognize their behaviors as problematic or may rationalize them as a means of coping with stress or controlling their weight. This lack of insight can make it challenging for them to seek help or receive proper treatment for their condition.

Which of the following types of cells is the immune system's shutoff mechanism?
- A. Plasma cells
- B. Suppressor T cells
- C. Helper T cells
- D. B lymphocytes
Correct Answer: B
Rationale: Suppressor T cells, also known as regulatory T cells, play a critical role in regulating the immune response by acting as the immune system's shutoff mechanism. These cells help maintain immune tolerance and prevent overactivation of the immune system, thereby preventing autoimmune reactions and excessive inflammation. Suppressor T cells exert their immunosuppressive effects by inhibiting the function of other immune cells, such as effector T cells and B cells, and helping to control the overall balance of the immune system.
A classic full blown AIDS case is identified by clinical manifestations such as:
- A. Persistent generalized lymphadenopathy
- B. Sudden loss of weight, afternoon fever and general malaise
- C. Tumors and opportunistic infections
- D. Fever, weight loss, night sweats and diarrhea
Correct Answer: C
Rationale: A classic full-blown AIDS case is characterized by the presence of tumors and opportunistic infections due to the severe immunodeficiency caused by the human immunodeficiency virus (HIV). As the immune system becomes progressively weakened, the individual becomes highly susceptible to various infections and malignancies, which are typically not seen in individuals with a healthy immune system. The presence of tumors and opportunistic infections in an individual signifies the advanced stage of HIV infection and the progression to AIDS. The other options (A, B, D) are more general symptoms that can be seen in various stages of HIV infection and are not specific to a full-blown AIDS case.
Which strategies should the school nurse recommend implementing in the classroom for a child with attention deficit hyperactive disorder (ADHD)? (Select all that apply.)
- A. Schedule heavier subjects to be taught in the afternoon.
- B. Accompany verbal instructions by written format.
- C. Limit number of breaks taken during instructional periods.
- D. Allow more time for testing.
Correct Answer: B
Rationale: Accompany verbal instructions by written format: Children with ADHD may have difficulty retaining verbal instructions due to their distractibility and impulsivity. Providing written instructions alongside verbal ones can help reinforce the information and improve comprehension.
Hyperparathyroidism is caused by increased levels of thyroxine in blood plasma. A client with this endocrine dysfunction would experience:
- A. Heat intolerance and systolic
- B. Diastolic hypertension and widened hypertension pulse pressure
- C. Weight gain and heat intolerance
- D. Anorexia and hyper-excitability
Correct Answer: A
Rationale: Hyperparathyroidism is caused by increased levels of parathyroid hormone (PTH), not thyroxine. The effects of hyperparathyroidism include increased calcium levels in the blood, which can lead to symptoms such as heat intolerance and systolic hypertension. Systolic hypertension is when the top number in a blood pressure reading is elevated. This is why option A (heat intolerance and systolic hypertension) is the correct choice for a client with hyperparathyroidism. Options B, C, and D do not accurately reflect the symptoms associated with this endocrine dysfunction.
Nurse Norma's discharge teaching for Mr. Aurelio, diagnosed with heart failure, should stress the significance of:
- A. maintaining a sedentary lifestyle most of the day
- B. obtain daily weights at the same time
- C. walking 2 miles daily
- D. maintaining a high fiber die
Correct Answer: B
Rationale: Nurse Norma's discharge teaching for Mr. Aurelio, diagnosed with heart failure, should stress the significance of obtaining daily weights at the same time. Daily weights help monitor fluid retention, a key indicator of worsening heart failure. Sudden weight gain may signal fluid buildup in the body, while weight loss may indicate dehydration or treatment effectiveness. By obtaining daily weights at the same time each day, Mr. Aurelio can track changes and provide valuable information for his healthcare team to adjust his treatment plan accordingly. This practice is crucial in managing heart failure and preventing exacerbations.
