The major electrolytes in the extracellular fluid are:

Correct Answer: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.

Correct Answer: D

Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.

Correct Answer: A

Rationale: The correct answer is A: Check for signs of infection. This is crucial because chemotherapy weakens the immune system, increasing the risk of infections. Signs of infection such as fever, chills, sore throat, and cough should be closely monitored to prevent serious complications. Monitoring weight (B) and nutrition (C) are important but not as critical as detecting infections promptly. Checking for skin changes (D) is also important, but it is secondary to identifying and managing infections due to the immediate threat they pose to the client's health.

Correct Answer: D

Rationale: The correct answer is D. A client with renal disease must avoid foods high in potassium to prevent hyperkalemia, as the kidneys are unable to properly filter and excrete potassium. Foods high in potassium can lead to dangerous levels of potassium in the blood, which can be life-threatening for individuals with renal disease. Choice A is incorrect because a client receiving diuretic therapy may actually need to increase their potassium intake due to the potassium-wasting effects of diuretics. Choice B is incorrect as having an ileostomy does not necessarily affect potassium levels. Choice C is incorrect because clients with metabolic alkalosis may actually benefit from consuming foods high in potassium to help correct the acid-base imbalance.

Correct Answer: C

Rationale: The correct answer is C: Neutropenia. Chemotherapy can suppress bone marrow function, leading to a decrease in neutrophils (a type of white blood cell), causing neutropenia. This increases the risk of infection. Monitoring for signs of infection is crucial in patients receiving chemotherapy to prevent serious complications. Anemia (A) is a common side effect of chemotherapy but is not directly related to infection risk. Hyperkalemia (B) and hypocalcemia (D) are less likely to be immediate complications of chemotherapy compared to neutropenia.

Correct Answer: B

Rationale: Step 1: The nurse should prioritize collecting data based on the client's acuity to address immediate needs and ensure patient safety. Step 2: Acuity determines the urgency and intensity of care required, guiding the assessment focus. Step 3: Time available or client cooperation may influence the depth of assessment but do not dictate the data collected. Step 4: The onset of symptoms is important for history-taking but not the primary factor in determining assessment data.

Correct Answer: B

Rationale: The correct answer is B: Do not use underarm deodorant. This is important because deodorant can interfere with the mammogram results, leading to false readings. It is crucial to have a clean and uncontaminated image for an accurate diagnosis. Choice A is incorrect as it can affect the quality of the mammogram. Choices C and D are irrelevant to the mammography procedure and not necessary instructions for the client.

Correct Answer: A

Rationale: The correct answer is A: Assess vital signs. Vital signs provide crucial information on the client's overall condition and can help identify any life-threatening issues. Monitoring vital signs such as blood pressure, heart rate, respiratory rate, and temperature can guide immediate interventions and determine the urgency of further assessments or treatments. Administering oxygen (B) would be appropriate after assessing vital signs. Performing an ECG (C) may be indicated later but is not the priority in this acute situation. Monitoring serum glucose levels (D) is not typically the first assessment in a client with severe abdominal pain.

Correct Answer: A

Rationale: The priority nursing intervention for a client with asthma experiencing wheezing is to administer oxygen. Wheezing indicates airway constriction and decreased oxygenation, making oxygen crucial for adequate tissue perfusion. Administering oxygen helps improve oxygen levels, alleviate respiratory distress, and prevent hypoxemia. Applying a bronchodilator (Choice B) may be beneficial after oxygen is administered. Applying a cold compress (Choice C) is not indicated for asthma exacerbations, and encouraging deep breathing (Choice D) may worsen respiratory distress in a client with wheezing. In summary, administering oxygen is the priority intervention to address the immediate respiratory needs of the client with asthma and wheezing.
