QUESTION

what other  labs if any  would you ask for on the following case study . Please provide at least three references

This patient has a diagnosis of insomnia with a past medical history of DM, HTN, MDD, and now presents with insomnia and disturbed sleep following the death of her husband ten months ago. As her depression has gotten worse, so has her sleep hygiene. According to Blanner et al. (2021), six categories are associated with widowhood, mental health and well-being, physical health, social relations, activities, and practicalities. Keeping these categories in mind during the client interview is a critical component of this case.

Physical Exam etc.

I would have the client complete a full head-to-toe exam with the following labs, tests.

VS with weight,  CBC (wbc, hgb), CMP (SIADH), Liver panel, A1C (DM control/compliance), EKG (qt interval) (pt/inr), also a sleep study for apnea BMI is 33.2 (obese)

Differential diagnoses can include hypersomnia, anemia, anxiety, panic disorder, restless legs, apnea, parasomnias, chronic renal failure, diabetes related to renal syndrome, fibromyalgia, CHF, and CAD (Mai & Buysse, 2008). I believe that the patient is suffering from hypersomnia and is unable to shut down in the evening to ready herself for sleep. “Despite the frequent attention to hyperarousal in the literature, it is not frequently defined. In this report, we conceptualize hyperarousal as heightened physiologic, affective, or cognitive activity, which interferes with the natural “disengagement from the environment and decreases the likelihood of sleep” (Levenson et al., 2015, p. 1180).

ANSWER

In addition to the physical examination and history provided, there are several additional laboratory tests that would be beneficial in evaluating the patient’s condition. The following labs would provide valuable information to further assess the underlying causes and contributing factors to the patient’s insomnia:

Thyroid Function Tests (TFTs): Thyroid dysfunction, including both hypothyroidism and hyperthyroidism, can impact sleep patterns and contribute to insomnia. TFTs, including thyroid-stimulating hormone (TSH), free thyroxine (FT4), and free triiodothyronine (FT3), can help rule out thyroid-related causes of insomnia (Zimmermann & Kohrle, 2019).

Serum Ferritin and Iron Studies: Anemia, particularly iron deficiency anemia, can lead to restless legs syndrome (RLS) and sleep disturbances. Assessing serum ferritin levels and iron studies, including serum iron, total iron-binding capacity (TIBC), and transferrin saturation, can help identify iron deficiency as a potential cause of the patient’s symptoms (Trotti et al., 2018).

Polysomnography (Sleep Study): Given the patient’s obesity and the possibility of obstructive sleep apnea (OSA), a polysomnography or sleep study would be beneficial to evaluate the patient’s sleep architecture, respiratory events, and oxygen saturation levels during sleep. This can help determine if OSA or other sleep disorders are contributing to the patient’s insomnia symptoms (Kapur et al., 2017).
