Question

The nurse explains human immunodeficiency virus (HIV) to a client newly diagnosed with the condition. What is important for the nurse to tell the client?

Answer 1

Correct Answers:

"It is very easy to get infections as HIV suppresses the immune system."

Rationale :

💠 HIV attacks CD4+ T-helper lymphocytes, which coordinate immune defense.

💠 Destruction of these cells weakens the adaptive immune system, increasing infection risk.

💠 Opportunistic infections such as Pneumocystis jirovecii or tuberculosis become common.

💠 Antiretroviral therapy (ART) helps slow viral replication but does not cure the disease.

💠 Continuous immune monitoring and infection prevention education are vital for management.

Answer 2

Correct Answers:

Nicotine use
Breakfast intake

Rationale :

🔹 Nicotine use: Smoking relaxes the lower esophageal sphincter (LES), allowing acid reflux into the esophagus

🔹 Nicotine also increases gastric acid secretion and decreases salivation that neutralizes acid

🔹 Continuous smoking irritates the esophageal mucosa, worsening gastroesophageal reflux symptoms

🔹 Avoiding smoking is vital as it reduces symptom recurrence and aids mucosal healing

🔹 Nurses should promote smoking cessation and healthy habits in GERD clients

🔹 Breakfast intake: High-fat foods such as bacon and whole milk delay gastric emptying, worsening reflux

🔹 Fatty meals increase intra-abdominal pressure, allowing acid backflow

🔹 GERD patients should consume low-fat, small, frequent meals to minimize reflux risk

🔹 Avoiding lying down within 2 hours after meals prevents symptom flare-ups

🔹 Nurses should guide clients on dietary changes and trigger avoidance

Answer 3

Correct Answers:

Risk for falls because of dopamine imbalance.

Rationale :

🔷 Parkinson’s disease results from loss of dopamine-producing neurons in the substantia nigra

🔷 Dopamine deficiency causes muscle rigidity, tremor, and bradykinesia affecting coordination

🔷 Clients are at high risk for falls due to postural instability and slow reflexes

🔷 Levodopa therapy helps replace dopamine, improving movement control

🔷 Nursing care includes assistive devices, safety education, and fall precautions

Answer 4

Correct Answers:

Wash the affected area.

Rationale :

✳️ Immediate washing removes urushiol resin from poison ivy, preventing deeper skin absorption

✳️ Soap and water reduce spread and intensity of allergic dermatitis

✳️ Applying creams before cleansing traps irritants, worsening inflammation

✳️ Nurses should advise washing contaminated clothing and equipment to prevent re-exposure

✳️ Early cleansing minimizes itching, redness, and blister formation

Answer 5

Correct Answers:

Heatstroke

Rationale :

💎 Heatstroke occurs when thermoregulatory mechanisms fail and body temperature rises above 40°C

💎 The absence of sweating indicates failure of heat dissipation

💎 Neurological changes like confusion or loss of consciousness signal brain dysfunction

💎 This is a medical emergency requiring rapid cooling and IV fluid resuscitation

💎 Older adults and dehydrated individuals are at greatest risk during hot weather

Answer 6

Correct Answers:

Metabolic alkalosis

Rationale :

🔶 Prolonged vomiting causes loss of gastric acid (HCl) leading to an alkaline state

🔶 The pH increases while bicarbonate levels rise, producing metabolic alkalosis

🔶 The body compensates by slowing respirations to retain CO₂

🔶 Hypokalemia commonly accompanies this due to hydrogen–potassium ion exchange

🔶 Treatment includes fluid and electrolyte replacement and antiemetic administration

Answer 7

Correct Answers:

Disuse atrophy

Rationale :

🟢 Muscles not used for prolonged periods lose mass and strength due to protein degradation

🟢 Immobility or casting causes muscle fiber shrinkage and reduced contractility

🟢 It is a reversible process with regular exercise and physiotherapy

🟢 Nursing interventions include range-of-motion (ROM) and early mobilization

🟢 Long-term disuse can result in joint stiffness and functional decline

Answer 8

Correct Answers:

Cover the open area with an airtight bandage.

Rationale :

🔴 The open wound allows air entry into pleural space, leading to a sucking chest wound

🔴 Applying an occlusive dressing taped on three sides prevents further air from entering

🔴 This converts it into a closed pneumothorax and stabilizes breathing

🔴 Immediate oxygen therapy follows wound sealing to improve oxygenation

🔴 The nurse must then prepare for chest tube insertion to re-expand the lung

Answer 9

Correct Answers:

Sickle cell anemia

Rationale :

🟣 A genetic mutation produces hemoglobin S, which sickles under low oxygen conditions

🟣 Sickled cells clump and block vessels, causing pain and tissue ischemia

🟣 Repeated crises lead to organ damage and chronic anemia

🟣 Hydration, oxygen therapy, and pain management are key nursing priorities

🟣 Genetic counseling is recommended for family planning and education

Answer 10

Correct Answers:

Negative feedback

Rationale :

🟡 The hypothalamus–pituitary–thyroid axis regulates hormone balance via negative feedback

🟡 When thyroid hormones rise, they suppress TSH and TRH secretion

🟡 This prevents overproduction and maintains endocrine homeostasis

🟡 Disruption in this loop leads to hyperthyroidism or hypothyroidism

🟡 Nurses should teach clients that feedback systems maintain internal stability
