The nurse knows that many medications given to clients have predictable, secondary effects which may be harmful or may be beneficial. The nurse always includes these effects in client teaching.

A. This principle emphasizes the duty to do no harm. In the case of the client undergoing chemotherapy and experiencing severe side effects that significantly reduce their quality of life, the principle of nonmaleficence comes into question. Chemotherapy, while aimed at treating cancer, often causes substantial side effects that can impact a patient's well-being

BThis principle relates to fairness and equality in the distribution of resources, treatments, and outcomes. In the context of cancer treatment, justice could be considered in terms of ensuring equitable access to chemotherapy and supportive care, regardless of socioeconomic status or other factors.

C Fidelity refers to the duty to be faithful, keep promises, and maintain trust in the patient-nurse relationship. In this context, fidelity would involve the nurse advocating for the client's best interests, including addressing their concerns about the severe side effects of chemotherapy and their impact on quality of life.

D. Autonomy refers to respecting the right of the patient to make their own decisions about their care and treatment. In the context of cancer treatment, autonomy would involve ensuring that the client has sufficient information about their condition, prognosis, treatment options, and potential side effects to make informed decisions. However, autonomy may also be challenged when severe side effects significantly impact the client's ability to maintain their desired quality of life despite ongoing treatment.

B. pH 7.25, PaCO2 61, HCO3 26

pH is decreased (acidosis).

PaCO2 is elevated (61 mmHg), indicating respiratory acidosis (increased CO2 retention). HCO3 is slightly elevated (26 mEq/L), compensating for the respiratory acidosis.

A. pH 7.45, PaCO2 35, HCO3 22

pH is within normal range (7.35-7.45).

PaCO2 is slightly lower than normal (35 mmHg), indicating mild respiratory alkalosis. HCO3 (bicarbonate) is within normal range (22 mEq/L).

C. pH 7.23, PaCO2 27, HCO3 25

pH is decreased (acidosis).

PaCO2 is lower than normal (27 mmHg), indicating respiratory alkalosis (which is unlikely in the context of morphine overdose with hypoventilation).

HCO3 is within normal range (25 mEq/L).

D. pH 7.54, PaCO2 59, HCO3 26

pH is increased (alkalosis).

PaCO2 is elevated (59 mmHg), indicating respiratory acidosis (consistent with hypoventilation). HCO3 is slightly elevated (26 mEq/L), compensating for the respiratory acidosis.
