Answers

Answer 1

In the long run, working memory appears to be marginally improved by caloric restriction in healthy persons. New avenues for preventing and treating cognitive impairments are made possible by research into brain CR targets.

calorie restriction's impact on healthy, non-obese adults' working memory

Objective:We compare working memory performance on neuropsychological tests between a group of non-obese healthy subjects who have been on CR for two years and a group who have been on an ad libitum diet in order to assess the impact of CR on cognition (AL).

Methods: 220 participants with a BMI between 22 and 28 kg/m2 participated in this study, which was a component of the broader multicenter CALERIE investigation.

This trial compared 2 years of 25% CR and AL in parallel groups in 220 individuals across 3 sites. The Cambridge Neuropsychological Tests Automated Battery (CANTAB) for Spatial Working Memory (SWM), including the total number of errors (SWMTE), and strategy were the cognitive tests that were utilized (SWMS). Mood states, energy expenditure, perceived stress, and sleep quality were all considered to be potential modifiers.Analysis was done at the beginning and at months 12 and 24.

Results: After corrections, CR individuals showed a considerably larger improvement in working memory measured by the SWM compared to AL. At month 24, it was primarily caused by consuming less protein than other macronutrients.

Changes in energy expenditure, physical activity, and sleep quality all had an impact on SWM.

What characteristic of human goals is responsible for their “energizing effect”?

Answers

Answer:

The characteristic of human goals that is responsible for their "energizing effect" is that, by involving a series of created expectations and their emotional connection with the person, they are adrenaline-generating.

Adrenaline is a hormone that is released in large quantities in conditions that are perceived by the body as threatening to survival and therefore cause stress. Often this is accompanied by fear and anger. Cold, heat, hunger, thirst, pain, physical exertion and other things that disturb the balance in the body can also increase adrenaline production.

EHR systems are becoming extremely popular due to their benefits and advantages. These advantages include better quality of care, more accurate patient info, interoperability, increased efficiency, increased revenue, scalability, accessibility, customization, security, and support.

Based on the above advantages I noted; can you elaborate on one and why you think it is a good advantage for patient care?

Answers

EHR systems' accessibility to precise patient data significantly improves patient treatment. It improves decision making for healthcare professionals, lowers medical errors, and facilitates fast and effective therapeutic actions.

Advantages of EHR systems to patients

The accessibility of more precise patient data is one benefit of electronic health record (EHR) systems that considerably enhances patient care.

All patient data is kept in one place and made available to authorized healthcare practitioners using EHR systems. This implies that when making treatment decisions for a patient, doctors, nurses, and experts involved in their care can quickly and simply obtain the most current and comprehensive information. They have real time access to test findings, imaging reports, prescription histories, and other important information.

EHR systems frequently come with clinical reminders and decision support tools that can assist healthcare professionals in adhering to evidence-based recommendations and best practices.

A physician orders Lanoxin elixir qd for an 81-pound child based on 3.4 mcg/ kg/day. Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL. What volume should be administered per dose?

Answers

Answer:

Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily

Explanation:

The child weighs 81 pound. The weight of the child is needed to be converted from pound to kg.

1 kg= 2.2 pound

Therefore 81 pound = 81/2.2 kg = 36.8 kg

Since the child is to be administered bases on 3.4 mcg/ kg/day, the volume of Lanoxin elixir qd to be administered to the 81 pound (36.8 kg) in one day = 36.8 kg × 3.4 mcg/ kg/day = 125.12 ≅ 125 mcg

Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL, therefore 125 mcg = 125 mcg / 50 mcg/ml = 2.5 ml

Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily

Please Answer Fast Before Friday July 23, 2021. Sara, a 14-year-old, has come to the office for her school physical. She is very remote, moody, and unwilling to answer any questions you ask her as part of her physical exam. She seems to have changed a great deal in the past year, and is thinner, more unkempt, and lethargic. You notice also that her mother is constantly badgering her and rolling her eyes in exasperation at her lack of cooperation. What could you do to facilitate the examination and improve communication with Sara? What possible problems could Sara be experiencing? What should you do about the concerns that you have for Sara?

Answers

Answer:

Sara is likely suffering from depression

Explanation:

To facilitate the exam, ask the parent to wait in the waiting area so you and Sara can talk alone. This way Sara will feel more comfortable in discussion with you without her mother hovering.

Sara may be suffering from depression. Her mother's criticism and judgements may be making her feel down or never "good enough".

To address your concerns for Sara:

1. administer a depression screening such as the PHQ-9 depression test questionnaire. If you find Sara is indeed depressed or has thoughts of hurting herself or others, she will need prompt treatment from a qualified health professional.

2. If Sara does NOT have intentions of hurting herself and her behavior is related to parent conflict, friend conflict, etc. then get her permission to have a discussion with her mother about it.

3. provide Sara with local/national hotline for depression and any other mental health resources that are available in your area (therapists, psychiatrists, community centers, etc.)

4. Follow-up with Sara with another visit in a timely manner to access her mental health.
