A nurse is reviewing the laboratory results of a client who has DKA. The client's ABG results are pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L. The nurse should identify that these values indicate which of the following acid-base imbalances?
Respiratory alkalosis
Metabolic alkalosis
Metabolic acidosis
Respiratory acidosis
The Correct Answer is C
A nurse reviewing the laboratory results of a client who has DKA should identify that the client's ABG results of pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L indicate metabolic acidosis. Metabolic acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a low bicarbonate level (less than 22 mEq/L).
The other options are not correct.
a) Respiratory alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a low PaCO₂ (less than 35 mm Hg).
b) Metabolic alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a high bicarbonate level (greater than 26 mEq/L).
d) Respiratory acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a high PaCO₂ (greater than 45 mm Hg).

Correct Answer is B

Applying heat to the affected joints can help relieve pain and stiffness. A heating pad or warm compress can be used to apply heat to the hands.

a) Sleeping on a soft mattress is not mentioned as a way to manage osteoarthritis symptoms.
b) Aspirin should be taken with food or milk to reduce stomach irritation.
c) Exercising inflamed joints excessively can worsen symptoms. It is important to balance rest and activity.
Correct Answer is C
Explanation
Correct answer: C
A) Start the first patch on the seventh day of the menstrual cycle: The patch is typically applied on the first day of the menstrual cycle or the first Sunday after the menstrual period begins, not on the seventh day. This helps ensure effective contraception from the start of use.
B) The contraceptive effect will continue for 6 months following discontinuation of the medication: The contraceptive effect of the patch does not last for 6 months after discontinuation. Once the patch is removed and not replaced, hormone levels drop, and fertility can return relatively quickly, typically within a few days to weeks.
C) Apply the patch to the lower abdomen: The patch should be applied to clean, dry, and intact skin on areas such as the lower abdomen, upper outer arm, buttock, or upper torso (excluding the breasts). This location allows for consistent hormone absorption.
D) Expect to have a headache during the first month: While some individuals may experience headaches as a side effect of hormonal contraceptives, this is not an expected or guaranteed outcome. Any persistent or severe headache should be reported to the healthcare provider, as it could indicate other concerns.
