Which part of the brain controls breathing?
- A. Medulla
- B. Cerebrum
- C. Cerebellum
- D. Thalamus
Correct Answer: A
Rationale: The correct answer is A: Medulla. The medulla is located in the brainstem and plays a crucial role in controlling involuntary functions like breathing. It contains the respiratory center, which regulates the rate and depth of breathing. The medulla sends signals to the diaphragm and intercostal muscles to control breathing. The cerebrum (B) is responsible for higher brain functions, not breathing control. The cerebellum (C) coordinates movement and balance, not breathing. The thalamus (D) relays sensory information to the cerebral cortex, not involved in breathing regulation.

A patient’s chest x-ray examination indicates fluid in both lung bases. Which of the ff. signs or symptoms present during the nurse’s assessment most reflects these x-ray examination findings?
- A. Fatigue
- B. Peripheral edema
- C. Bilateral crackles
- D. Jugular vein distention
Correct Answer: C
Rationale: The correct answer is C, bilateral crackles. Fluid in both lung bases on x-ray indicates pulmonary edema, causing crackles on auscultation. Fatigue (A) is a nonspecific symptom. Peripheral edema (B) is a sign of fluid retention in the extremities, not lungs. Jugular vein distention (D) indicates increased central venous pressure, which is not specific to lung fluid.
After reviewing the database, the nurse discovers that the patient’s vital signs have not been recorded by the nursing assistive personnel (NAP). Which clinical decision should the nurse make? Administer scheduled medications assuming that the NAP would have reported
- A. abnormal vital signs. Have the patient transported to the radiology department for a scheduled x-ray, and
- B. review vital signs upon return.
- C. Ask the NAP to record the patient’s vital signs before administering medications.
- D. Omit the vital signs because the patient is presently in no distress.
Correct Answer: C
Rationale: Rationale for Correct Answer (C): Asking the NAP to record the patient's vital signs before administering medications is the correct clinical decision. Vital signs are crucial indicators of a patient's health status and should be documented before any interventions. By having the NAP record the vital signs, the nurse ensures that the patient's condition is properly assessed and monitored. This action aligns with the standard of care and promotes patient safety.
Summary of Incorrect Choices:
A: Administering medications without knowing the patient's vital signs could be dangerous, especially if there are abnormalities that need attention.
B: Reviewing vital signs upon return delays necessary assessment and intervention, potentially compromising patient safety.
D: Omitting vital signs without assessment puts the patient at risk, as changes in vital signs can indicate underlying issues that need immediate attention.
Nursing assessment for a patient with metabolic alkalosis includes evaluation of laboratory data for all of the following except:
- A. Hypocalcemia
- B. Hypokalemia
- C. Hypoglycemia
- D. Hypoxemia
Correct Answer: C
Rationale: The correct answer is C: Hypoglycemia. In metabolic alkalosis, the blood pH is elevated due to an excess of bicarbonate. Hypoglycemia is not directly related to metabolic alkalosis but can be seen in other conditions like diabetes or fasting. Evaluating for hypocalcemia (A) is important as alkalosis can lead to decreased ionized calcium levels. Hypokalemia (B) is common in metabolic alkalosis due to potassium loss. Hypoxemia (D) is not directly related to metabolic alkalosis but can occur in severe cases due to respiratory compensation. Therefore, hypoglycemia is the least relevant in assessing metabolic alkalosis.
When taking the blood pressure of a client who has AIDS the nurse must;
- A. Wear a mask and gown
- B. Use barrier techniques
- C. Wash the hands thoroughly
Correct Answer: B
Rationale: The correct answer is B: Use barrier techniques. When taking the blood pressure of a client with AIDS, using barrier techniques such as gloves and disposable equipment is crucial to prevent the transmission of the virus through blood or bodily fluids. Wearing a mask and gown (choice A) may not be necessary unless there is a risk of splashes or sprays. Washing hands thoroughly (choice C) is important, but alone may not provide sufficient protection. Choice D is incomplete.
Many neuromuscular disorders can impair respiratory function. What intervention can a home care nurse recommend to help prevent complications in patients with impaired respiratory function?
- A. Antibiotics as needed
- B. Bedrest
- C. Elevate the head of bed
- D. Suction q4h
Correct Answer: C
Rationale: The correct answer is C: Elevate the head of bed. Elevating the head of the bed helps improve lung expansion and ventilation, making it easier for patients with impaired respiratory function to breathe. This position also helps prevent aspiration and reduces the risk of respiratory complications. Antibiotics (choice A) are not indicated unless specifically prescribed for an infection. Bedrest (choice B) can lead to deconditioning and worsen respiratory function. Suctioning (choice D) every 4 hours is not necessary unless there is excessive secretions present.
