A patient’s serum sodium is within normal range. The nurse estimates that serum osmolality should be:
- A. Less than 136mOsm/kg
- B. Greater than 408mOsm/kg
- C. 280 to 295mOsm/kg
- D. 350 to 544mOsm/kg
Correct Answer: C
Rationale: The correct answer is C (280 to 295mOsm/kg) because serum osmolality is primarily determined by sodium, glucose, and blood urea nitrogen levels. Normal serum sodium range is 135-145 mEq/L, which corresponds to an osmolality range of 280-295 mOsm/kg. Choices A and B are incorrect as they do not align with normal serum sodium levels. Choice D is incorrect as it includes an excessively wide range that is not consistent with normal osmolality values.

A nurse develops a nursing diagnostic statement for a patient with a medical diagnosis of pneumonia with chest x-ray results of lower lobe infiltrates. Which nursing diagnosis did the nurse write?
- A. Ineffective breathing pattern related to pneumonia
- B. Risk for infection related to chest x-ray procedure NursingStoreRN
- C. Risk for deficient fluid volume related to dehydration
- D. Impaired gas exchange related to alveolar-capillary membrane changes
Correct Answer: D
Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This is the most appropriate nursing diagnosis for a patient with pneumonia and lower lobe infiltrates. The rationale is that pneumonia causes inflammation and fluid accumulation in the alveoli, impairing the exchange of oxygen and carbon dioxide in the lungs. This directly affects gas exchange.
Choice A is incorrect because ineffective breathing pattern is a broad nursing diagnosis that does not specifically address the underlying issue of impaired gas exchange in pneumonia. Choice B is incorrect as the risk of infection related to the chest x-ray procedure is unrelated to the patient's current condition of pneumonia. Choice C is also incorrect as dehydration does not directly correlate with the patient's diagnosis of pneumonia and lower lobe infiltrates.
Mrs. Zeno asks the nurse why the disease has occurred. The nurse bases the reply on the knowledge that there is:
- A. A genetic defect in the production of acetylcholine
- B. A reduced amount of neurotransmitter acetylcholine
- C. A decreased number of functioning acetyl-choline receptor sites
- D. An inhibition of the enzyme Ache leaving the end plates folded.
Correct Answer: C
Rationale: The correct answer is C because a decreased number of functioning acetylcholine receptor sites would result in the disease. Acetylcholine is a neurotransmitter that transmits signals between nerves and muscles. If there are fewer receptor sites for acetylcholine to bind to, this can lead to impaired nerve-muscle communication, causing the disease.
Choice A is incorrect because a genetic defect in acetylcholine production would not directly affect the receptor sites. Choice B is incorrect because a reduced amount of acetylcholine would still be able to bind to the available receptor sites. Choice D is incorrect because inhibiting the enzyme Ache would not directly impact the receptor sites.
A client reports difficulty breathing, stating, 'I can’t catch my breath.' What is the most appropriate action for the nurse to take?
- A. Validate the client’s statement by measuring oxygen saturation.
- B. Encourage the client to perform deep breathing exercises.
- C. Document the client’s statement and continue with the assessment.
- D. Provide oxygen immediately without further assessment.
Correct Answer: A
Rationale: The correct answer is A because measuring oxygen saturation will provide objective data to assess the client's respiratory status accurately. This step is crucial in identifying the severity of the client's breathing difficulty and determining the appropriate intervention. Encouraging deep breathing exercises (B) may worsen the client's condition if there is an underlying respiratory problem. Simply documenting the client's statement (C) without immediate action can delay necessary interventions. Providing oxygen without further assessment (D) can be harmful if the client's oxygen saturation is already high. Overall, option A is the most appropriate as it involves a proactive and evidence-based approach to address the client's reported breathing difficulty.
The nurse is gathering data on a patient. Which data will the nurse report as objective data?
- A. States “doesn’t feel good”
- B. Reports a headache
- C. Respirations 16
- D. Nauseated
Correct Answer: C
Rationale: Objective data are measurable and observable facts. Respirations (C) of 16 per minute is objective data as it is a quantifiable measurement that can be counted and recorded. It is not influenced by personal interpretation or bias. Choices A, B, and D are subjective data as they rely on the patient's feelings, perceptions, or symptoms, which can vary and are open to interpretation. Therefore, choice C is the correct answer as it represents concrete, verifiable information that can be used in the patient's assessment and care planning.
An adult is being taught about a healthy diet. How can the food pyramid help guide the client on his diet?
- A. By indicating exactly how many servings of each group to eat
- B. By calculating how many calories the client should have
- C. By suggesting daily food choices
- D. By dividing the food into four basic groups
Correct Answer: C
Rationale: The correct answer is C because the food pyramid suggests daily food choices based on the different food groups. It provides a visual guide on the proportions of each food group to consume for a balanced diet. It does not specify the exact number of servings (A), calculate calories (B), or divide food into four basic groups (D). The food pyramid is a tool to help individuals make healthier food choices by emphasizing variety and moderation.
