After the nurse teaches the client with stage 1 hypertension about diet modifications.Which diet choice indicates that the teaching has been most effective?

Correct Answer: A

Rationale: The correct answer is A because avoiding salted nuts helps reduce sodium intake, which is crucial for managing hypertension. Salt can increase blood pressure. Choice B is incorrect as chicken and fish can be part of a healthy diet. Choice C is incorrect as sugary beverages can worsen hypertension. Choice D is incorrect as excessive caffeine intake can raise blood pressure. In summary, choice A is the most effective as it directly addresses reducing sodium intake, which is essential for managing hypertension.

Correct Answer: C

Rationale: The correct answer is C: PN2 = 620mmHg. This is the inconsistent value because the normal partial pressure of nitrogen in venous blood is around 40 mmHg, not 620 mmHg. This discrepancy indicates an abnormal measurement. The other choices (A, B, D) are within expected ranges for a mixed venous blood sample in a healthy person at sea level. Choice A (pO2 = 40mmHg) is typical for venous blood, choice B (pCO2 = 48mmHg) falls within the normal range, and choice D (O2 content = 150ml/L blood) is a reasonable value for mixed venous blood.

Correct Answer: B

Rationale: The correct answer is B: external respiration. This is the part of respiration where oxygen and carbon dioxide are exchanged in the capillaries lining the alveoli in the lungs. During external respiration, oxygen from the alveoli diffuses into the bloodstream while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. A: Pulmonary ventilation refers to the process of breathing, specifically the movement of air in and out of the lungs. This does not involve the actual exchange of gases in the alveoli. C: Transport of respiratory gases involves the movement of oxygen and carbon dioxide through the bloodstream to and from the tissues. This is not specifically related to the exchange of gases in the alveoli. D: Internal respiration refers to the exchange of gases between the bloodstream and the tissues at the cellular level. This does not specifically occur in the alveoli of the lungs.

Correct Answer: C

Rationale: The correct answer is C: Increased pulmonary capillary permeability. ARDS is characterized by damage to the alveolar-capillary membrane, leading to increased permeability and leakage of fluid into the alveoli. This causes bilateral white-outs on X-ray. Cardiogenic pulmonary edema (A) results from heart failure, not ARDS. Respiratory alkalosis (B) is a condition of elevated blood pH due to hyperventilation, not a direct cause of ARDS. Renal failure (D) is not a direct cause of ARDS, although it can contribute to fluid overload. Thus, the most accurate choice is C due to the pathophysiological mechanism of ARDS.

Correct Answer: B

Rationale: The correct answer is B: Non-rebreather mask. This device provides the highest concentration of oxygen among the choices, around 80-100%. In a client with difficulty breathing and low oxygen saturation, a high concentration of oxygen is crucial to quickly reverse hypoxemia. The non-rebreather mask ensures that the client is receiving the maximum amount of oxygen with each breath, improving oxygenation rapidly. A: Simple mask delivers a lower concentration of oxygen and would not be sufficient for a client in distress. C: Face tent does not provide a high concentration of oxygen and may not be effective in quickly reversing hypoxemia. D: Nasal cannula delivers a lower concentration of oxygen compared to the non-rebreather mask and may not be enough to reverse manifestations in a client with significant difficulty breathing and low oxygen saturation.
