1. What are the key signs of hyperkalemia and how should it be treated?

A. Elevated potassium levels, muscle weakness; administer calcium gluconate
B. Decreased potassium levels, confusion; administer potassium chloride
C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
D. Low sodium levels, muscle cramps; administer sodium chloride

Correct answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

2. What are the key components of a respiratory assessment?

A. Inspection, Palpation, Percussion, Auscultation
B. Inspection, Observation, Auscultation, Percussion
C. Auscultation, Palpation, Observation, Percussion
D. Observation, Palpation, Percussion, Auscultation

Correct answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment involves inspecting the chest for symmetry and signs of distress, palpating for tenderness or abnormal masses, performing percussion to assess underlying tissues, and auscultating lung sounds. Choice B is incorrect as observation is a broad term that can encompass both inspection and palpation. Choice C is incorrect as auscultation is usually performed after inspection and palpation. Choice D is incorrect as observation should be more specific, and auscultation is a key component that is typically done last in a respiratory assessment.

3. Which of the following is an early indicator that suctioning is needed for a client with a tracheostomy?

A. Bradycardia
B. Hypotension
C. Irritability
D. Confusion

Correct answer: C

Rationale: Irritability is an early indicator that suctioning is needed for a client with a tracheostomy because it can signal discomfort or difficulty breathing due to mucus accumulation, prompting the need for suctioning to clear the airway. Bradycardia (Choice A) and hypotension (Choice B) are not typically early indicators of the need for suctioning in a client with a tracheostomy. Confusion (Choice D) is also not a direct early indicator of the need for suctioning in this context.

4. What are the signs and symptoms of Cushing's syndrome, and how should they be managed?

A. Weight gain, moon face; administer corticosteroids
B. Hirsutism and thin extremities; manage with diuretics
C. Purple striae, muscle weakness; provide dietary counseling
D. Hypertension and bruising; manage with fluid restriction

Correct answer: A

Rationale: The correct signs and symptoms of Cushing's syndrome are weight gain and a moon face. Corticosteroids are used to manage Cushing's syndrome by reducing the overproduction of cortisol. Choice B is incorrect because hirsutism and thin extremities are not typical signs of Cushing's syndrome. Choice C is incorrect as purple striae and muscle weakness are more characteristic of the syndrome. Choice D is also incorrect as hypertension and bruising are not primary signs of Cushing's syndrome.

5. What is the best nursing intervention for a patient with hyperkalemia?

A. Administer potassium-wasting diuretics
B. Encourage a low-potassium diet
C. Administer potassium supplements
D. Administer IV fluids

Correct answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.
