ATI Pathophysiology
1. A client with heart failure is experiencing pulmonary edema. Which intervention should be prioritized?
- A. Administer diuretics to reduce fluid overload.
- B. Position the client in high-Fowler's position.
- C. Administer oxygen therapy to improve oxygenation.
- D. Restrict fluid intake to prevent further fluid overload.
Correct answer: C
Rationale: In a client experiencing pulmonary edema due to heart failure, the priority intervention is to administer oxygen therapy to improve oxygenation. This helps in increasing the oxygen levels in the blood, thereby improving tissue perfusion and reducing the workload on the heart. Positioning the client in high-Fowler's position can also aid in improving oxygenation, but administering oxygen therapy directly addresses the immediate need for increased oxygen levels. Administering diuretics to reduce fluid overload and restricting fluid intake are important interventions in heart failure management, but in the acute situation of pulmonary edema, oxygen therapy takes precedence to ensure adequate oxygen supply to vital organs.
2. Which of the following is a factor that leads to increased risk for dehydration in the elderly?
- A. More insensible losses
- B. Increase in muscle mass
- C. Decline in kidney function
- D. Decrease in fat
Correct answer: C
Rationale: The correct answer is C: Decline in kidney function. As people age, their kidneys may not work as effectively in conserving water and concentrating urine, leading to a higher risk of dehydration. Choice A is incorrect because more insensible losses do not directly relate to an increased risk of dehydration in the elderly. Choice B, an increase in muscle mass, is not a factor that leads to dehydration. Choice D, a decrease in fat, is also not a direct factor contributing to dehydration in the elderly.
3. During an assessment of a male client suspected of having a disorder of motor function, which finding would suggest a possible upper motor neuron (UMN) lesion?
- A. Hypotonia
- B. Hyperreflexia
- C. Muscle atrophy
- D. Fasciculations
Correct answer: B
Rationale: Hyperreflexia, or exaggerated reflexes, is a common sign of an upper motor neuron (UMN) lesion. An UMN lesion indicates damage to the central nervous system pathways that control movement. Hypotonia (choice A) refers to reduced muscle tone, which is more indicative of lower motor neuron lesions. Muscle atrophy (choice C) suggests long-standing denervation or disuse of muscles. Fasciculations (choice D) are involuntary muscle contractions that can be seen in lower motor neuron lesions, like in amyotrophic lateral sclerosis (ALS), rather than UMN lesions.
4. During a well-child checkup, a mother tells Nurse Rio about a recent situation in which her child needed to be disciplined by her husband. The child was slapped in the face for not getting her husband breakfast on Saturday, despite being told on Thursday never to prepare food for him. Nurse Rio analyzes the family system and concludes it is dysfunctional. All of the following factors contribute to this dysfunction except:
- A. Conflictual relationships between parents.
- B. Inconsistent communication patterns.
- C. Rigid, authoritarian roles.
- D. Use of violence to establish control.
Correct answer: C
Rationale: In a dysfunctional family system, conflictual relationships, inconsistent communication patterns, and the use of violence to establish control are factors contributing to dysfunction. However, rigid, authoritarian roles, though also dysfunctional, are not directly linked to the use of violence for control.
5. Which electrolyte imbalance does the nurse suspect in a patient with hyperaldosteronism?
- A. Hyponatremia
- B. Hypernatremia
- C. Hyperkalemia
- D. Hypercalcemia
Correct answer: C
Rationale: In a patient with hyperaldosteronism, the nurse would suspect hyperkalemia. Hyperaldosteronism leads to increased potassium excretion, resulting in low potassium levels in the blood. Therefore, choices A (Hyponatremia), B (Hypernatremia), and D (Hypercalcemia) are incorrect. Hyponatremia refers to low sodium levels, Hypernatremia refers to high sodium levels, and Hypercalcemia refers to high calcium levels, none of which are typically associated with hyperaldosteronism.
