Question 1 of 9

After providing discharge teaching, a nurse assesses the clients understanding regarding increased risk for metabolic alkalosis. Which statement indicates the client needs additional teaching?

Correct Answer: C

Rationale: The correct answer is C because taking sodium bicarbonate after every meal can actually increase the risk of metabolic alkalosis due to its alkaline nature. Sodium bicarbonate can lead to an excessive build-up of bicarbonate in the bloodstream, causing alkalosis. Choice A is not directly related to metabolic alkalosis. Choice B, taking digoxin, is unrelated to metabolic alkalosis as well. Choice D, drinking six glasses of water due to sweating, does not contribute to metabolic alkalosis as it helps maintain hydration and electrolyte balance.

Question 2 of 9

The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

Correct Answer: B

Rationale: The correct answer is B because considering potential effects on the patient's mobility is crucial when selecting a site for IV insertion. Mobility can be affected if the IV is placed in a joint area or on the dominant hand. This could limit the patient's ability to move freely during and after the procedure. Therefore, it is important to choose a site that will not hinder the patient's movement. A: Choosing a hairless site is not the most important factor when selecting a site for IV insertion. C: Having the patient hold his arm over his head before insertion is not necessary and may cause discomfort for the patient. D: Leaving the tourniquet on for at least 3 minutes is not recommended as it can lead to complications such as venous stasis.

Question 3 of 9

. You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patients plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to as

Correct Answer: D

Rationale: The correct answer is D: Fluid volume status. Assessment of specific gravity helps to determine the concentration of solutes in the urine, indicating the degree of hydration or dehydration. In SIADH, there is water retention leading to diluted urine, resulting in low specific gravity. Monitoring specific gravity every 4 hours is crucial in assessing the patient's fluid volume status and response to treatment. A: Nutritional status is not directly assessed by specific gravity. B: Potassium balance is not directly assessed by specific gravity. C: Calcium balance is not directly assessed by specific gravity.

Question 4 of 9

. A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?

Correct Answer: D

Rationale: The correct answer is D. A cool lower extremity can indicate impaired circulation due to the intraosseous catheter placement, leading to compartment syndrome or tissue necrosis. This finding requires immediate intervention to prevent serious complications. Choices A, B, and C are incorrect because the duration of catheter placement, poor vascular access, and the specific location of the catheter do not directly impact circulation and tissue perfusion as significantly as a cool lower extremity.

Question 5 of 9

The nurse is providing care for a patient with chronic obstructive pulmonary disease. When describing the process of respiration the nurse explains how oxygen and carbon dioxide are exchanged between the pulmonary capillaries and the alveoli. The nurse is describing what process?

Correct Answer: A

Rationale: The correct answer is A: Diffusion. In respiration, oxygen and carbon dioxide are exchanged between the alveoli and pulmonary capillaries through the process of diffusion. Here's the rationale: 1. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. 2. In the alveoli, oxygen moves from the air (higher concentration) into the blood (lower concentration) and carbon dioxide moves from the blood (higher concentration) into the air (lower concentration). 3. This exchange occurs passively, without the need for energy input, which is characteristic of diffusion. Summary of other choices: B: Osmosis involves the movement of water across a semi-permeable membrane, not gas exchange. C: Active transport requires energy input to move molecules against their concentration gradient, not seen in gas exchange. D: Filtration involves the movement of molecules through a membrane under pressure, not the passive movement of gases in respiration.

Question 6 of 9

A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?

Correct Answer: B

Rationale: The correct answer is B: Sodium bicarbonate 100 mEq diluted in 1 L of D5W. In this case, the client is experiencing metabolic acidosis due to low HCO3 levels (16 mEq/L) with a low pH (7.28). Sodium bicarbonate helps correct metabolic acidosis by increasing the HCO3 levels. Furosemide (A) is a diuretic and can worsen the client's electrolyte imbalance. Mechanical ventilation (C) is not indicated for metabolic acidosis. Indwelling urinary catheter (D) does not address the underlying acid-base imbalance. Therefore, the nurse should expect the provider to order sodium bicarbonate to correct the metabolic acidosis.

Question 7 of 9

After teaching a client who was malnourished and is being discharged, a nurse assesses the clients understanding. Which statement indicates the client correctly understood teaching to decrease risk for the development of metabolic acidosis?

Correct Answer: A

Rationale: The correct answer is A: "I will drink at least three glasses of milk each day." Milk is a good source of calcium and bicarbonate, which can help buffer excess acids in the body and prevent metabolic acidosis. Calcium also plays a role in maintaining the acid-base balance. Option B is incorrect because while eating well-balanced meals is important for overall health, it does not specifically address the prevention of metabolic acidosis. Option C is irrelevant to the prevention of metabolic acidosis. Option D is incorrect because avoiding salting food does not directly address the underlying issue of metabolic acidosis related to malnutrition.

Question 8 of 9

After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?

Correct Answer: C

Rationale: The correct answer is C because it includes foods high in potassium. Raisins, whole wheat toast, and milk are good sources of potassium. Sausage might contain some potassium as well. A: This option lacks potassium-rich foods. B: While strawberries have some potassium, the overall meal lacks a sufficient amount. D: While oatmeal and peaches have potassium, coffee can actually inhibit potassium absorption.

Question 9 of 9

A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

Correct Answer: A

Rationale: The correct assessment for the nurse to complete first is A: Depth of respirations. Potassium and magnesium levels are crucial electrolytes that can affect cardiac function. Hypokalemia (low potassium) and hypomagnesemia (low magnesium) can lead to cardiac dysrhythmias. Checking the depth of respirations can provide valuable information on the client's respiratory status and potential respiratory distress due to electrolyte imbalances. This assessment takes precedence as addressing respiratory issues promptly is essential to prevent further complications. Assessing bowel sounds (B), grip strength (C), and electrocardiography (D) are important but not as immediate as assessing respiratory status in this scenario.
