How to combine multiple ranges with getRange in order to clear the contents of specific cells?

I use this sheet to enter data of patients in (Data_Entry) tab. Specific rows are titles and should not be cleared whenever I clear contents of all cells in the sheet/tab. Like Rows 1-4 and rows 20-21. So I made this script to clear specific cells but it seems very basic and it has a problem whenever somebody inserts a new row in between, the whole range needs to be adjusted.

The script has three functions: adding_menu, making borders of query results in (All_patients)tab and ClearContents of (Data_Entry) tab.

So my question is about the last function (ClearContent)

 function onOpen() {    var menuItems = [    {name: 'ClearContents', functionName: 'ClearContents'},    {name: 'Borders', functionName: 'borders'}  ];  SpreadsheetApp.getActiveSpreadsheet().addMenu('Weekened_Functions', menuItems);}function borders() {  var range = SpreadsheetApp.getActive().getSheetByName('All_Patients').getDataRange();  var cell = SpreadsheetApp.getActive().getSheetByName('All_Patients').getRange("B50:H200")  cell.setBorder(false, false, false, false, false, false);  var values = range.getValues();  for (var i = 2; i < values.length; i++) {    for (var j = 1; j < values[i].length; j++) {        range.getCell(i + 1, j + 1).setBorder(true, true, true, true, true, true);      }    }  }function ClearContents() {  var sheet = SpreadsheetApp.getActive().getSheetByName('Data_Entry');  sheet.getRange('B5:F19').clearContent(),  sheet.getRange('B22:F34').clearContent();  sheet.getRange('B37:F49').clearContent();  sheet.getRange('B52:F64').clearContent();  sheet.getRange('B67:F83').clearContent();  sheet.getRange('B86:F102').clearContent();  sheet.getRange('B105:F119').clearContent();  sheet.getRange('B122:F133').clearContent();  sheet.getRange('B136:F146').clearContent();  sheet.getRange('B149:F160').clearContent();  sheet.getRange('B163:F174').clearContent();  sheet.getRange('B177:F188').clearContent();  sheet.getRange('B191:F202').clearContent();  sheet.getRange('B205:F216').clearContent();  sheet.getRange('B219:F230').clearContent();  sheet.getRange('B247:F257').clearContent();  sheet.getRange('B260:F269').clearContent();  sheet.getRange('M5:M19').clearContent(),  sheet.getRange('M22:M34').clearContent();  sheet.getRange('M37:M49').clearContent();  sheet.getRange('M52:M64').clearContent();  sheet.getRange('M67:M83').clearContent();  sheet.getRange('M86:M102').clearContent();  sheet.getRange('M105:M119').clearContent();  sheet.getRange('M122:M133').clearContent();  sheet.getRange('M136:M146').clearContent();  sheet.getRange('M149:M160').clearContent();  sheet.getRange('M163:M174').clearContent();  sheet.getRange('M177:M188').clearContent();  sheet.getRange('M191:M202').clearContent();  sheet.getRange('M205:M216').clearContent();  sheet.getRange('M219:M230').clearContent();  sheet.getRange('M247:M257').clearContent();  sheet.getRange('M260:M269').clearContent();  sheet.getRange('H5:H19').clearContent(),  sheet.getRange('H22:H34').clearContent();  sheet.getRange('H37:H49').clearContent();  sheet.getRange('H52:H64').clearContent();  sheet.getRange('H67:H83').clearContent();  sheet.getRange('H86:H102').clearContent();  sheet.getRange('H105:H119').clearContent();  sheet.getRange('H122:H133').clearContent();  sheet.getRange('H136:H146').clearContent();  sheet.getRange('H149:H160').clearContent();  sheet.getRange('H163:H174').clearContent();  sheet.getRange('H177:H188').clearContent();  sheet.getRange('H191:H202').clearContent();  sheet.getRange('H205:H216').clearContent();  sheet.getRange('H219:H230').clearContent();  sheet.getRange('H247:H257').clearContent();  sheet.getRange('H260:H269').clearContent();};

1\ how to combine these ranges in simple formula?

2\ Is there a way to add exception like: (clear contents of all cells except Column M and Column A and cells containing text "Ward" or "room"or problem list" or "recommendations"?
