NCLEX RN Predictor Exam

1. Each small square on the EKG paper is:

A. 0.04 seconds long and 5mm tall
B. 0.2 seconds long and 5mm tall
C. 0.04 seconds long and 20mm tall
D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

2. A patient's urine tests positive for glucose. The doctor asks you to confirm this finding. Which of the following would BEST confirm this finding?

A. Run the urine on the hand-held glucometer.
B. Have another MA perform a repeat dipstick test.
C. Run a Clinitest.
D. Run an Acetest.

Correct answer: C

Rationale: To confirm glucosuria, the most appropriate method is to run a Clinitest. Clinitest tablets are specifically designed to detect glucose in urine samples. This test is particularly useful when the urine is discolored, making it challenging to accurately assess the color change.\n Choice A, using a hand-held glucometer, is not the standard method for confirming glucose in urine; these devices are primarily used for blood glucose monitoring.\n Choice B, having another Medical Assistant perform a repeat dipstick test, may not provide a more definitive confirmation as dipstick tests can sometimes yield false positives or be less accurate compared to other methods like the Clinitest.\n Choice D, running an Acetest, is used to detect ketones in the urine, not glucose. Ketones are typically associated with conditions like diabetic ketoacidosis, which is different from glucosuria.

3. The hospital has sounded the call for a disaster drill on the evening shift. Which of these clients would the nurse prioritize first on the list to be discharged in order to make a room available for a new admission?

A. A middle-aged client with a history of being ventilator dependent for over seven (7) years and admitted with bacterial pneumonia five days ago.
B. A young adult with diabetes mellitus Type 2 for over ten (10) years and admitted with antibiotic-induced diarrhea 24 hours ago.
C. An elderly client with a history of hypertension, hypercholesterolemia, and lupus, and was admitted with Stevens-Johnson syndrome that morning.
D. An adolescent with a positive HIV test and admitted for acute cellulitis of the lower leg 48 hours ago.

Correct answer: A

Rationale: The best candidate for discharge during a need for emergency room availability is a stable patient with a chronic condition who is familiar with their care. In this scenario, the middle-aged client in option A, who has been ventilator dependent for over seven years and admitted with bacterial pneumonia five days ago, is most suitable for discharge. This client is likely stable and can continue medication therapy at home, making them the most appropriate choice for discharge at this time. Choice B should not be the priority for discharge as the young adult with diabetes mellitus Type 2 admitted with antibiotic-induced diarrhea 24 hours ago may need further monitoring and management of their condition. Choice C, the elderly client with multiple comorbidities and admitted with Stevens-Johnson syndrome on the same day, is not a suitable candidate for immediate discharge as they may require ongoing medical attention and observation. Choice D, the adolescent with a positive HIV test and admitted for acute cellulitis of the lower leg 48 hours ago, should not be discharged first as acute cellulitis may require continued treatment and monitoring, especially in the context of a positive HIV status.

4. Madge is a 91-year-old nursing home resident with a history of dementia and atrial fibrillation who has been admitted to the hospital for treatment of pneumonia. As you are performing her bed bath, you note bruising around her breasts and genital area. What potential issue should be of major concern in Madge's situation?

A. Idiopathic thrombocytopenic purpura (ITP)
B. Embolic stroke
C. Sexual abuse
D. Nursing home-acquired pneumonia (NHAP)

Correct answer: C

Rationale: Bruising around the breasts and genitals should trigger concern for sexual abuse. Elder abuse is a growing problem in America, and nurses are uniquely positioned to recognize and intervene on behalf of vulnerable populations, such as the elderly. According to the National Center on Elder Abuse (NCEA), major types of elder abuse include physical abuse, sexual abuse, emotional or psychological abuse, neglect, abandonment, financial or material exploitation, and self-neglect. In this scenario, given Madge's age, history of dementia, and the presence of unexplained bruising in sensitive areas, sexual abuse must be considered as a major concern. Idiopathic thrombocytopenic purpura (ITP) is a platelet disorder that presents with excessive bruising and bleeding, but it is less likely in this case as the bruising pattern is suggestive of a different cause. Embolic stroke is a neurological condition that typically presents with sudden onset neurological deficits and is not related to the observed bruising. Nursing home-acquired pneumonia (NHAP) is a common issue in elderly residents but would not manifest as bruising in specific areas like the breasts and genitals.

5. Digestion, elimination, and ___________ are the three functions of the digestive system.

A. constriction
B. relaxation
C. absorption
D. peristalsis

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.
