Question

The nurse observes that the client's urine is dark yellow and appears very concentrated. The lab test that would correlate with this data would be a, high urine specific gravity. b. low hemoglobin and hematocrit. c. elevated WBC count. d. proteinuria.

Short answer

The correct answer is (a) high urine specific gravity, as it measures the concentration of solutes in the urine, which correlates with the observation of dark yellow and concentrated urine.

Step-by-step solution

Understand Urine Observations

The nurse observes that the urine is dark yellow and appears very concentrated. Dark yellow urine typically indicates that the urine has a high concentration of solutes.

Correlation with Lab Test

Urine specific gravity is a lab test that measures the concentration of all chemical particles in the urine. Given the observation of dark yellow, concentrated urine, the lab test that would correlate with this data would be a test that measures concentration, which is urine specific gravity.

Eliminate Irrelevant Options

The other options mentioned (low hemoglobin and hematocrit, elevated WBC count, and proteinuria) are not directly related to the concentration of urine. Hemoglobin and hematocrit levels are related to blood, an elevated WBC count indicates infection or inflammation, and proteinuria refers to the presence of an abnormal amount of protein in the urine.

Key concepts

Urine Concentration

Understanding urine concentration is essential when analyzing a patient's hydration status and kidney function. Urine specific gravity is a measurement that compares the density of urine to the density of water, providing an estimation of how concentrated a person’s urine is. A higher urine specific gravity suggests that the urine contains a large amount of solutes, which can be due to various factors such as decreased water intake, excessive fluid loss, or the body’s response to conserve water in dehydration scenarios.

The concentration of urine is reflected in its color; darker urine typically indicates higher concentration levels. Consistent observations of dark yellow urine can be a sign of inadequate hydration and may necessitate further investigation. Nurses should encourage fluid intake and monitor for changes in urine color as part of routine patient care. It is also valuable for nurses to educate patients about the implications of urine color changes as part of self-care practices.

Nursing Assessment

A thorough nursing assessment incorporates clinical observations with laboratory data to form a comprehensive picture of a patient's health. When a patient presents with dark yellow, concentrated urine, the nursing assessment would consider the patient's recent fluid intake, presence of any symptoms such as thirst or dizziness, and their overall health status.

Furthermore, the nurse would correlate these findings with relevant lab tests to confirm or rule out potential health issues. As detailed earlier, a high urine specific gravity would support the assessment of concentrated urine. In contrast, tests like hemoglobin and hematocrit are connected to blood quality, while elevated WBC count suggests infection and proteinuria is linked with kidney function, none of which are directly related to urine concentration itself.

An accurate nursing assessment is pivotal, as it forms the basis for any subsequent medical interventions, education, or referrals that may be necessary.

NCLEX-RN Examination

For nurses preparing to take the NCLEX-RN examination, understanding how to assess urine concentration and its clinical implications is essential. The exam tests the knowledge and skills necessary for safe and effective nursing practice. Questions related to urine concentration could fall under the scope of physiological integrity, one of the primary content areas of the exam. Being proficient in lab test interpretation, including urine specific gravity, is vital for success on the NCLEX-RN.

It is important for candidates to not only recognize what specific lab tests measure but also how to apply this knowledge to patient scenarios. Nurses must be adept at linking clinical signs, such as dark yellow urine, with appropriate lab tests to guide decision-making. Candidates are often presented with patient cases and asked to identify the most relevant assessments or actions, thus emphasizing the importance of critical thinking in nursing practice.
