Exam Cram NCLEX RN Practice Questions

1. Which of these guidelines would a healthcare professional follow when measuring a patient's weight?

A. The patient is always weighed wearing only undergarments.
B. The type of scale matters and should be consistent day to day.
C. The patient should remove heavy outer clothing, shoes, and jackets before weighing.
D. Attempts should be made to weigh the patient at approximately the same time of day if a sequence of weights is necessary.

Correct answer: D

Rationale: When measuring a patient's weight, it is important to ensure accuracy and consistency. If a sequence of repeated weights is necessary, the healthcare professional should attempt to weigh the patient at the same time of day and with the same types of clothing worn each time. It is crucial to use a standardized balance or electronic standing scale for accurate weight measurement. Choice A is incorrect as patients should remove heavy outer clothing, shoes, and jackets before being weighed for accurate results. Choice B is incorrect because the type of scale used does matter and should be consistent for reliable weight tracking. Choice C is incorrect as patients should not leave on heavy outer clothing, shoes, or jackets as these items can add to the weight recorded inaccurately.

2. Which of the following is a negative outcome associated with impaired mobility?

A. Increased amounts of calcium are absorbed from circulation
B. A drop in blood pressure occurs when rising from a sitting to a standing position
C. The amount of mucus in the bronchi and lungs decreases
D. The vessel walls of the circulatory system thicken

Correct answer: B

Rationale: A client with impaired mobility may develop changes in body systems that put them at risk of further illness or injury. One negative outcome associated with impaired mobility is orthostatic hypotension, where blood pressure drops significantly when moving from a sitting or lying position to a standing position. This drop in blood pressure can lead to symptoms such as dizziness or fainting. This occurs because blood circulates more slowly or pools in the distal extremities due to impaired mobility. Choice A is incorrect because increased calcium absorption is not a typical negative outcome associated with impaired mobility. Choice C is incorrect because a decrease in mucus in the bronchi and lungs is not a common negative outcome of impaired mobility. Choice D is incorrect because thickening of vessel walls in the circulatory system is not directly associated with impaired mobility.

3. In which of these patients would rectal temperatures be measured?

A. Older adult
B. Critically ill patient
C. School-age child
D. Patient receiving oxygen via nasal cannula

Correct answer: B

Rationale: Rectal temperature measurement is preferred in situations where other routes are impractical or when the most accurate measure is necessary, such as in critically ill patients. The rectal route may be chosen due to its reliability in such cases. For older adults, school-age children, and patients receiving oxygen via nasal cannula, rectal temperature measurement is not typically indicated. Other routes like oral, tympanic, or axillary measurements are more commonly used in these populations due to comfort, convenience, and non-invasive nature.

4. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?

A. The admission orders are written.
B. A blood culture is drawn.
C. A complete blood count with differential is drawn.
D. The parents arrive.

Correct answer: B

Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.

5. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?

A. Pituitary
B. Pineal
C. Pancreas
D. Hypothalamus

Correct answer: B

Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.
