A nurse is reviewing the laboratory results of a client who has bulimia nervosa. The nurse should notify the provider of which of the following results?
WBC 5.200/mm3.
Hgb 14 g/dL.
Potassium 3.2 mEq/L.
Magnesium 1.6 mEq/L.
The Correct Answer is C
Choice A rationale:
A white blood cell (WBC) count of 5,200/mm3 is within the normal range, which typically varies but is approximately 4,500-11,000/mm3. This result indicates a normal immune response and does not require provider notification.
Choice B rationale:
A hemoglobin (Hgb) level of 14 g/dL falls within the normal range for adults, which is generally between 12-16 g/dL for women and 13.5-17.5 g/dL for men. This result is not a cause for concern, and the nurse does not need to notify the provider about it.
Choice C rationale:
A potassium (K+) level of 3.2 mEq/L is considered hypokalemia. The normal range for potassium is around 3.5-5.0 mEq/L. Hypokalemia can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. The nurse should notify the provider to address this electrolyte imbalance promptly.
Choice D rationale:
A magnesium (Mg) level of 1.6 mEq/L is below the normal range of approximately 1.7-2.2 mEq/L. While mild hypomagnesemia might not require immediate intervention, it's important to monitor and potentially address this electrolyte imbalance, especially if the client's symptoms worsen. However, it does not warrant immediate notification of the provider.

Correct Answer is D
Explanation
Choice A rationale:
Canned potato soup is not a suitable choice for a heart-healthy diet. Canned soups often contain high levels of sodium, which can contribute to hypertension and worsen coronary artery disease.
Choice Brationale:
Baked ham is another poor choice for a heart-healthy diet. Processed meats like ham tend to be high in sodium, saturated fats, and preservatives, which can negatively impact cardiovascular health.
Choice Crationale:
Processed cheese is also not recommended for a heart-healthy diet. Processed cheese can be high in saturated fats and sodium, both of which are detrimental to cardiovascular health.
Choice D rationale:
The correct choice is broiled salmon. Salmon is rich in omega-3 fatty acids, which have been shown to have protective effects on the heart. Omega-3 fatty acids can help lower triglyceride levels, reduce inflammation, and improve overall cardiovascular health. Broiling the salmon is a heart-healthy cooking method that preserves its nutritional value without adding excessive unhealthy fats.
Correct Answer is B
Explanation
Choice A rationale:
A temperature of 37.2°C (99°F) is within the normal range (approximately 36.5°C to 37.5°C or 97.7°F to 99.5°F) and does not specifically indicate fluid volume deficit. It's important to consider this value along with other findings.
Choice B rationale:
(Correct Choice) A pulse rate of 118/min is indicative of tachycardia, which can be a sign of fluid volume deficit. When the body is experiencing a decrease in fluid volume, the heart rate often increases as a compensatory mechanism to maintain adequate circulation. Tachycardia helps to pump a reduced blood volume more rapidly to vital organs.
Choice C rationale:
A blood pressure of 152/90 mm Hg is elevated but does not solely indicate a fluid volume deficit. While low blood pressure can be a sign of dehydration, high blood pressure does not necessarily correlate directly with fluid volume status.
Choice D rationale:
Central venous pressure (CVP) of 25 mm Hg is elevated. CVP reflects the pressure in the vena cava and right atrium, indicating the amount of blood returning to the heart. An elevated CVP might be seen in fluid volume excess or right-sided heart failure, not fluid volume deficit.
