NURA 303 NCLEX EXAM 3 COMPLETE AND VERIFIED QUESTIONS WITH CORRECT ANSWERS ||100% PASS .Which of the following are considered cardinal signs of infection? (select all that apply) A) Swelling B) Redness C) Pain D) Loss of function E) Cyanosis F) Pallor A, B, C, D (Rationale: The cardinal signs of infection are swelling, redness, pain, and loss of function, all of which indicate an inflammatory response. Cyanosis and pallor are not signs of infection but could indicate circulation issues or hypoxia.) .A nurse is caring for an elderly client who is at risk for a pulmonary infection. What age-related factor is most likely contributing to the risk of infection? A) Decreased renal blood flow B) Decreased activity of cilia in the respiratory tract C) Decreased immune response D) Incomplete emptying of the bladder B (Rationale: In the elderly, the decreased activity of cilia in the respiratory tract impairs the body's ability to clear microorganisms from the airway, increasing the risk of pulmonary infections. While other factors are relevant, decreased ciliary action is directly linked to respiratory infections.) .A nurse is performing patient education about preventing urinary tract infections (UTIs) in older adults. Which of the following factors increase the risk for UTI? (select all that apply) A) Incomplete emptying of the bladder B) Pelvic floor relaxation due to estrogen depletion C) Increased elastic recoil of the lungs D) Enlarged prostate gland E) Increased vascular supply to the skin A, B, D (Rationale: Older adults are at increased risk for UTIs due to incomplete bladder emptying, pelvic floor relaxation from estrogen depletion, and enlarged prostate gland in males. These factors contribute to urinary stasis, which fosters bacterial growth. The lungs and skin are unrelated to UTIs.) .Which of the following is the first line of defense against infection? A) White blood cells B) Skin and mucous membranes C) Antibodies D) Inflammatory response B (Rationale: The skin and mucous membranes act as the body's first physical barriers to infection by blocking the entry of pathogens. White blood cells, antibodies, and the inflammatory response are part of the body's secondary defense mechanisms.) .You are assessing a client for infection. The patient reports burning during urination and a foul-smelling odor. Based on this assessment, what should the nurse suspect? A) Pulmonary infection B) Urinary tract infection C) Skin infection D) Viral infection B (Rationale: Burning during urination and foul-smelling urine are classic symptoms of a urinary tract infection (UTI). Pulmonary infections usually present with cough and shortness of breath, and skin infections typically involve redness and swelling at the site.) .Which of the following are important steps in preventing the spread of infection in a healthcare setting? (select all that apply) A) Use gloves when touching body fluids B) Wash hands before and after patient contact C) Recap needles carefully D) Wear a mask when dealing with airborne precautions E) Share equipment between patients if sanitized A, B, D (Rationale: Proper hand hygiene and wearing gloves when in contact with body fluids are critical infection control practices. Masks are necessary for airborne precautions. Recapping needles and sharing equipment are unsafe practices that increase the risk of needle sticks and cross-contamination.) .A nurse is developing a care plan for a client at risk for infection. What is the priority outcome for this client? A) The client will verbalize knowledge of infection control procedures. B) The client will maintain skin integrity. C) The client will show no signs or symptoms of infection during hospitalization. D) The client will report reduced stress levels. C (Rationale: The priority outcome is that the client remains free from infection during hospitalization, as infection can complicate the client's health status. Verbalizing knowledge is important but does not guarantee infection prevention.) .Drag-and-Drop: Put the steps in the correct order Place the steps for donning personal protective equipment (PPE) in the correct order: Gown Gloves Mask Face shield Gown - Mask - Face shield - Gloves (Rationale: Donning PPE follows a specific order to reduce contamination risk. The gown goes on first, followed by the mask, face shield, and gloves (gloves go over the gown cuffs to prevent skin exposure).) .Which precaution should a nurse take when caring for a patient with tuberculosis? A) Contact precautions B) Droplet precautions C) Airborne precautions D) Standard precautions C (Rationale: Tuberculosis (TB) is spread through airborne transmission, so airborne precautions are required, including using a respirator mask and placing the patient in a negative pressure room.) .A nurse is caring for a patient with a catheter. Which action should the nurse implement to reduce the risk of a catheter-associated urinary tract infection (CAUTI)? A) Limit fluid intake to prevent overflow B) Perform perineal hygiene at least once a day C) Use a double-lumen catheter D) Apply antiseptic ointment to the catheter insertion site B (Rationale: Performing perineal hygiene at least once a day reduces the risk of CAUTI by keeping the area around the catheter clean. Antiseptic ointments and limiting fluids are not recommended strategies for CAUTI prevention.)
