The nurse has determined that a client with trigeminal neuralgia has the nursing problem, "Imbalanced nutrition, less than body requirements." Which cause is most likely contributing to the problem?

Fatigue.

Pain when eating.

Nausea.

Altered taste sensation.

Answer and Explanation

The Correct Answer is B

A.   While fatigue can contribute to decreased appetite, it is not as directly linked to the specific condition of trigeminal neuralgia.
B.   Trigeminal neuralgia is characterized by severe, sharp facial pain, often triggered by chewing, talking, or even a gentle breeze. This pain would significantly deter a person from eating, leading to imbalanced nutrition.
C.   Nausea is not a typical symptom of trigeminal neuralgia and would not be the primary cause of imbalanced nutrition in this case.
D.   While altered taste can affect food enjoyment, it is less likely to completely deter someone from eating compared to the intense pain associated with trigeminal neuralgia.

Correct Answer is B

Explanation

A. Hematocrit measures the proportion of blood volume that is occupied by red blood cells. A hematocrit of 33% is lower than the normal range (42% to 52% for males and 37% to 47% for females). While this indicates anemia and reduced oxygen-carrying capacity of the blood, it is not directly related to the risk for infection.
B. White blood cells (WBCs) are crucial for the immune system and fighting infections. A WBC count of 1,500/mm³ is significantly below the normal range (5,000 to 10,000/mm³). This low WBC count, also known as leukopenia, indicates a decreased ability to fight infections, making the client highly susceptible to infections.
C. Hemoglobin measures the oxygen-carrying capacity of red blood cells. A hemoglobin level of 10 g/dL is below the normal range (14 to 18 g/dL), indicating anemia. While anemia affects overall health and can contribute to fatigue and weakness, it does not directly indicate the risk for infection.
D. The red blood cell (RBC) count measures the number of red blood cells in the blood. A count of 3.5 x 10^12/L is below the normal range (4.2 to 5.4 x 10^12/L), indicating a reduction in red blood cells and anemia. Like low hemoglobin, this value indicates anemia but does not directly reflect the risk for infection.

A. Calcium level 7.2 mg/dL (1.8 mmol/L). B. Potassium level 3.8 mg/dl. (3.8 mmol) C. Sodium level 140 mEq/L (140mmol/L). D. Oxygen saturation level 97%.

Correct Answer is A

Explanation

A. This calcium level is below the normal reference range (8.4 to 10.6 mg/dL or 2.10 to 2.50 mmol/L), indicating hypocalcemia. Calcium plays a crucial role in cardiac muscle contraction and electrical conduction. Low calcium levels can lead to various cardiac dysrhythmias, including prolonged QT intervals and increased risk of ventricular arrhythmias.

B. This potassium level falls within the normal range (3.5 to 5.0 mEq/L or 3.5 to 5.0 mmol/L). Potassium is essential for maintaining normal cardiac rhythm, but a level of 3.8 mg/dL is not abnormal and, therefore, is less likely to be the cause of a dysrhythmia compared to abnormal levels.
C. This sodium level is within the normal reference range (136 to 145 mEq/L or 136 to 145 mmol/L). Sodium levels typically do not directly cause dysrhythmias unless they are extremely high or low, which is not the case here. Thus, a sodium level of 140 mEq/L is not likely to be the primary contributor to the dysrhythmia.
D. This oxygen saturation level is considered normal (95% to 100%). While oxygenation is critical for overall heart function and can influence cardiac health, a saturation level of 97% is not likely to be a direct cause of a dysrhythmia, especially if it falls within the normal range.
