Correct Answers | Latest Update 2026 | Nursing Exam
Prep
1. What is the primary cause of neurogenic shock?
Pneumonia
Heart attack
Spinal cord injury
Severe allergic reaction
2. Water intoxication can lead to
Hypernatremia
Hyponatremia
Dehydration
Fat gain
Shriveled cells
3. Describe how airway obstruction affects respiratory function.
Airway obstruction increases airflow, enhancing oxygen delivery.
Airway obstruction impairs airflow, leading to difficulty in breathing
and reduced oxygen intake.
Airway obstruction has no effect on respiratory function.
Airway obstruction only affects the circulatory system.
4. Causes of Cheyne-stokes breathing include 1. Central sleep apnea 2.
Meningitis 3. Congestive heart failure 4. Increased intracranial pressure

5. What is the normal range for blood pH in a healthy individual?
7.0 to 7.5
6.5 to 7.0
7.0 to 7.4
7.35 to 7.45
6. Describe how respiratory disturbances can impact overall blood
composition.
Respiratory disturbances do not significantly affect blood
composition.
Respiratory disturbances primarily affect blood pressure regulation.
Respiratory disturbances only impact the pH level of the blood.
Respiratory disturbances can lead to altered oxygen and carbon
dioxide levels in the blood, affecting gas exchange.
7. Metabolic acidosis disturbances would be reflected by plasma
HCO3 excess and increased H+ concentration
HCO3 deficit and increased H+ concentration
HCO3 deficit and increased pH
H2CO3 excess and increased pH
,8. In a patient presenting with chest pain and a pleural friction rub, what would
be the most appropriate next step in management?
Further diagnostic imaging to assess for pleuritis or pleural effusion
Initiation of broad-spectrum antibiotics
Immediate administration of anticoagulants
Referral for cardiac evaluation
9. A patient has just received a right mastectomy due to a severe diagnosis of
breast cancer. Which of the following has the risk of occurring after surgery?
Lymphedema
Inflammatory Edema
Hydrostatic Edema
Oncotic Edema
10. Describe the significance of maintaining a normal blood pH range for
overall health.
Blood pH has no significant impact on health.
A lower pH indicates better oxygen transport in the blood.
Blood pH only affects respiratory health.
Maintaining a normal blood pH range is crucial for proper enzyme
function and metabolic processes.
11. Describe the significance of tidal volume in assessing respiratory health.
Tidal volume measures the oxygen saturation levels in the blood.
Tidal volume indicates the total lung capacity and is used to diagnose
lung diseases.
, Tidal volume is crucial for evaluating lung function and ensuring
adequate ventilation.
Tidal volume is irrelevant in assessing respiratory health.
12. If a patient presents with symptoms of muscle weakness and arrhythmias,
what might you suspect regarding their potassium levels?
Hyperkalemia (high potassium levels)
Dehydration
Hypokalemia (low potassium levels)
Normal potassium levels
13. The most common sign or symptom of lung cancer is:
Hoarseness
Dyspnea
Hemoptysis
Persistent cough
14. Describe how metabolic disturbances can influence the overall health of an
individual.
Metabolic disturbances only affect the respiratory system.
Metabolic disturbances have no significant impact on health.
Metabolic disturbances primarily affect the production of red blood
cells.
Metabolic disturbances can lead to imbalances in pH levels,
affecting organ function and overall health.
15. Which body system is primarily affected by lymphoma?
