D. Metabolic alkalosis Answer: C. Common causes of metabolic acidosis include alcohol or ethanol intoxication, diabetic ketoacidosis, hypoxia, kidney failure, diarrhea, and pancreatitis.
deplete magnesium levels. Which one can you deplete magnesium level(SATA)? Nasogastric losses due to suctioning Fistula drainage Diarrhea
which of the Following mechanisms should the nurse expect the clients body to use? Hyperventilation
Rationale: The nurse should instruct the client about using pursed-lip breathing during periods of dyspnea to slow expiration, increase airway pressure, and facilitate effective gas exchange.
Rationale B: Excreting bicarbonate causes acidosis to develop. Rationale C: Retaining carbon dioxide causes respiratory acidosis. Rationale D: Excreting carbon dioxide causes respiratory alkalosis
A: A client who has a new diagnosis of adrenal insufficiency. B: A client who has a heart failure. C: A client who is receiving treatment for diabetic ketoacidosis. D: A client who has abdominal ascites. Answer: B. The nurse should anticipate a client who has heart failure to require fluid and sodium restriction to reduce the workload on the heart
Answer: A. seizure Rationale A: Severe hyponatremia can lead to seizures. Seizure precautions such as a quiet environment, raised side rails, & having an oral airway at the bedside would be included. Rationale B: Infection precautions not specifically indicated for a pt with hyponatremia. Rationale C: Neutropenic precautions not specifically indicated for a pt with hyponatremia. Rationale D: High-risk fall precautions not specifically indicated for a pt with hyponatremia. The patient is experiencing hyponatremia. What treatment does the nurse anticipate? Fluid restriction
Answer: B. Respiratory acidosis is a common complication for COPD. It occurs when patients are unable to exhale carbon dioxide due to a loss of elastic recoil in the lungs.
B. Provide nasal oxygen C. Have him breath into a paper bag D. Have him cough and deep breath Answer C: Breathing into a paper bag helps the father to “rebreathe” some of the carbon dioxide that he is losing because he is hyperventilating. This will help correct the blood pH. Panting will contribute to respiratory alkalosis.
imbalances? A. Respiratory acidosis B. Respiratory alkalosis C. Metabolic acidosis D. Metabolic alkalosis Answer: C. Metabolic acidosis. Rationale: Acid retention increases with advancing CKD. The client develops Kussmaul respirations (increase in depth and rate) to promote excretion of carbon dioxide through the lungs.
B. Decreased potassium level C. Elevated magnesium level D. Decreased calcium level Answer: B. Hypokalemia is an electrolyte imbalance in which the serum potassium level is less than 3.5 mEq/L. Hypokalemia may be the result of diuretic use, diarrhea, vomiting, and prolonged nasogastric suctioning Common manifestations of potassium depletion include.(SATA)? Weak & irregular pulse muscle weakness fatigue Ventricular dysrhythmias.
E. Tachypnea Answer A B D E A. lack of fluid results in dryness of skin and decrease turgor B. urine is concentrated due to lack of fluid in the vascular system. D. low grade fever one of body ways to maintain homeostasis to compensate for lack of fluid E. increased respirations obtain oxygen due to lack of fluid
D. Phosphorus level of 2. Answer - C. Hypokalemia (normal potassium levels are 3.5 to 5.1) will present with these type of EKG findings. The patients potassium level is 5.2. When the LVN discusses dietary selections, the patient should be instructed to limit intake of what food items. (SATA)? Kiwi Tomatoes Orange juice Bananas
